Coral Propagation and
Pharmaceuticals 4/26/09
HI ,
First off, thanks for having such a great web site. It's helped me in
many ways over the years. This is actually my first time emailing
you...so here goes....
I'm looking for information on commercial coral propagation for
pharmaceutical companies. Does this even exist?
<Mmm, likely so... though as far as I'm aware, such efforts are
proprietary. Am out in CO and have been chatting with another presenter,
Christine Williams, who works for such a large co. doing such searches
in marines... Will cc her here and ask that she chime in if she has
something to say>
I realize that wild caught can be cheaper, but organisms raised under
controlled conditions can be much more desirable for research. I
searched Google and your FAQ's but found very limited information about
this topic. I'm well familiar with culturing corals in a greenhouse
setting. Looks like a logical step in propagation and business.
Thanks,
John

Neon Candy Cane Frag Mounting a Caulastrea Frag 9/24/08
Hello, <hi> I have a 24 gal Aquapod, been up and running for 4
months everything is going great with the tank. Last week I bought a
neon candy cane frag. My question is on how to get the coral onto the
live rock. I read numerous entries and I understand about the super glue
attachment way. But how do I get the candy cane off of the piece of
material that it is attached to when you buy it from the LFS? Do you cut
it off of that piece (looks like an oversized golf tee) the coral is
attached to? I am getting how to put them on the LR but I am not clear
on how to transfer it. Thanks for any help! <Aaron you have a few
options. Easiest would be to just jam that frag plug, (the golf tee
looking thing) into a crack in the rocks and either epoxy it with
something like Aquamend that you can get at your local hardware store,
or super glue gel. Your goal is just to hold it secure so the various
tank critters in your tank don’t knock it loose. Over time coralline
algae will cover the plug and you won’t see it anymore. Your second
option is to remove it from the plug by force, either by cutting it or
breaking it at the base near the plug and doing the same gluing process
on the rocks. I personally prefer the first method> Aaron<Regards,
Jessy> Larger Scale
Live Rock Alternative – 07/09/08 Crew, <<Hey Ryan>> Thank
you for providing such an extensive resource to our community, your
service is second to none. <<Thank you much for the kind
words…redeeming indeed>> I have read and re-read most of what has
already been published here regarding different types of live rock
"substitutes", (i.e. cinder blocks, lava rock, homemade, etc.), <<I
see>> and our problem/situation is on a bit of different scale than
those discussed thus far. <<Oh?>> We are in need of a much larger
volume of rock, and due to the obvious costs, etc., are in search of ANY
reliable alternatives. <<Mmm, I understand…but do realize there is no
real “alternative” to live rock, only poor substitutes of varying
degree>> We currently operate a coral propagation facility with
roughly 1,300 gallons and 1,000lbs of rock that has been in our tanks
for years. Well-seeded, to say the least. <<Maybe so…but also likely
in need of a “boost”>> January 1st, we are expanding to a new
location, with roughly 5,000g planned, and would like to get "whatever
it is we are going to use" for rock/bio, to start seeding in our current
system right away. <<Some of your existing rock will serve well as a
start-up bacteria culture…but after “years” is low in soluble
bio-mineral content and alkaline reserve…as well as diminished
bio-diversity>> We have the time and space now to start whatever
"curing" process is going to be needed before introducing it into the
current system, but we are concerned about the long term effects of
items like cinder blocks, etc. leaching at the new shop. <<The
biggest immediate concern is elevated pH (as high as 12.0 and above with
new “cement” products), but this is easily “cured” down to acceptable
levels…though the process can be lengthy (8 weeks or more). Long term
issues in my experience with cement-based rock are excessive/problematic
nuisance alga growth…and the fact that it provides no real bio-mineral
content or buffer capacity/alkaline reserve>> So, my 2 questions
are... Is there any truth to the different "soaking" methods
(vinegar) to prevent this effect? <<The vinegar will not “prevent”
anything…rather, the Acetic Acid can be useful in “speeding up” the
curing process. I have no personal experience with this method as I have
always just used a plain water-soak, and from what I have heard, the
added cost/trouble is little worth it. But do feel free to give it a try
and decide for yourself>> In dealing with something on this scale,
has any rock substitute been proven reliable on a long term basis?
<<Terrestrial limestone may well be your best choice here. It will be
much more dense/heavy than good live rock, will not support as much
bacteria load as live rock, and brings nothing to the table re
bio-diversity…but can be bought cheaply in bulk, and is a more “natural”
source than the cement-based products (e.g. – cinderblock)…and though
you will need to test to be sure, it will not likely need “curing.” With
the limestone, do consider utilizing as much “new live rock” as you can
to provide those needed elements the limestone can’t provide…perhaps as
much as a fifth of the total volume (but the more the better!)…doing so
will also make the limestone “better”>> Thank you for all that you
folks do. Ryan Haag <<We are happy to assist. Eric Russell>>
Airlifts? 4/23/08 Good morning! I am doing research of airlifts
for water circulation in large 4'x18'x2'deep tanks for coral
propagation. <Oh, Dick Perrin uses this water-movement mechanism in
his facility... Tropicorium > I have scoured the internet and WWM and
have not found any places that show the functionality of a large scale
airlift system. <Mmm, there's a bunch... in the engineering end for
destratification systems for lakes, ponds... but you'll have to make a
trip to a large (college) library> I know that many people have used
them on systems similar to this. Thank you for your time. Andrew
Lawing <Maybe a call or email to Aquatic Ecosystems... or Argent
Chemicals (the first for general reference, glass airstones... the
second for their large collection of in-print materials. Bob Fenner>
Please forward to Bob Fenner. Thanks! Greenhouse coral farming 04/22/08
Bob, <Andrew!> I just wanted to write you a quick note to say
thanks for coming down to give us that presentation here in San Antonio.
<Welcome my friend> I enjoyed it very much and I do have to say you
have had me researching an ozonizer as well. I was the guy that you met
at the store on Saturday and my girlfriend worked at PETCO. <Ah yes,
I recall. The NAV recruiter!> Thank you for you inspiration. Now on
to the question. I have been researching the feasibility of greenhouse
farming for about one year and I am very interested in it and your talk
and my recent activities in the Hobby have excited me even more. I guess
the biggest thing I have yet to plan out is overcoming the heat here in
central Texas, but I am working on figuring that out. <Can be done in
a few ways... best to shoot for redundancy, and the cheapest, most
reliable means> This is a project that is still in the planning
phases and nowhere near ready to build. I wonder might you have some
advice on greenhouse farming? <A bunch... though unfortunately not
put altogether in articles per se... but strung out by topic, e.g.
cooling/chilling water, on WWM> So far I have searched around the
internet and come up with some very good idea, however I could not find
any information on Anthony Calfo's greenhouse. <Am pretty sure he's
written quite a bit re in the vol. 1, first and second Ed.s of "Book of
Coral Propagation"... have you seen this book?> Thanks for your time
Bob and I look forward to you coming back to down Texas again. Andrew
Lawing <Keep accumulating those plans Andrew... Bob Fenner>
Re: Please forward to Bob Fenner. Thanks! Greenhouse reef farming
04/22/08 Thanks for the advice on the book I will pick it up
ASAP, and once again thanks from MAAST! Have a good day <Thank you
Andrew. I do hope to visit your operational facility come MACNA XXII in
San Antonio. Bob Fenner>
Coral Glue And Coral Light Absorption (Photoperiod) – 04/12/08
Awhile ago I got a couple of corals that came with a silicone type
glue that mounted them to the rock. At the time, I didn't think it
would be so good and don't recall where I got these corals. This
glue bonds to rock just by placing it on top of it. I have tried to
locate this material at all the tropical shops in my area but no one
carries it or knows what it is. It is not "super glue" or putty - it
stays flexible and doesn't need to be reapplied. Can you help? What
is it and where can I get it? <<I can only guess, but there are
some better “underwater epoxies” that remain flexible. These
products form a molecular bond that is quite tenacious. They’re
quite pricey too…at around $50 per quart>> On the coral's light
absorption - how many hours of light do they really need daily using
optimum lighting? <<”Optimum lighting” will vary by species…but
lighting in the tropics where most all specimens we strive to keep
hail from averages a bit more than 12-hours per day…and at an
intensity we can only dream of replicating>> Does it vary by type
of coral? <<Indeed>> I have polyp types, leathers, frogspawns,
elegance and coral plates. Thank you. <<I suggest you provide a
lighting period of somewhere between 10 and 14 hours per
day…depending on quality/intensity of the lighting. EricR>>
Re: Coral Glue And Coral Light Absorption (Photoperiod) – 04/15/08
Can you give me the name(s) of some safe underwater epoxies? And
where I might purchase? Thank you! <<I assume you refer to
the “flexible” epoxy mentioned previously. I’ve not attempted to use
any of these myself nor can I vouch for their “safeness,” and as was
previously stated, can only guess that this was the material you
were describing in the first place. But...a simple Google search of
the NET re “flexible underwater epoxy” or “thickened epoxy” does
turn up some sources if you wish to pursue. One source that provides
a wide array of many types of adhesives is ELLSWORTH Adhesives
(http://www.ellsworth.com/adhesives.html?tab=Products), and if you
are interested in a flexible Cyanoacrylate (Super Glue) see here
(http://news.thomasnet.com/fullstory/29449). Regards, EricR>> |
Coral Propagation/Home Business 3/7/08 Hey there crew! <Hi
Ryan> This is a terrific site! I have not seen so much quality
information on reefs anywhere on the web. Thanks you for your hard work.
<You're welcome.> I have had aquariums my whole life. For several
years, while I was in college, I bred African cichlids, angelfish, and
discus for extra money. I still have many of the same LFS contacts so I
think I will be able to develop a strong coral business too. My
question is in regards to a 20 gallon long propagation tank that I am in
the process of setting up. My plan is to start with some extra mushrooms
that I have in my display tank. Profit is not an concern, <Good,
since there won't be much.> I just want to develop a working system
and gain an understanding of what I am doing before I increase my
operation to a "large" scale home business. I just want your comments on
any improvements I can make. My plan is to have a 2-3 inch substrate
depth, two power heads with low gph (<150), Prizm skimmer, Penguin 150
filter, 130 watts of compact florescent lighting (dual bulbs
10000k/6700k). <The lighting should be fine for most softies.> I
have ready Anthony's newest book and much of the information on this
site that is relevant to what I am planning. Any help will be greatly
appreciated!! <The profit margin on a home coral propagation business
is usually just enough to offset the expense. Is done more for the love
of the hobby and to offset hobby expenses. I would suggest the use of
Rubbermaid Tubs for this purpose. One hanging MH fixture will easily
illuminate the entire tub where all types of coral can be grown. Is best
to keep coral families in separate tubs to reduce allelopathy. Most
folks doing this use plastic eggcrate to place their frags on. Shrooms
can be lightly rubberbanded to rubble rock until they attach. Aragonite
plugs are now sold and hard coral frags can be super glued to the plug
and placed into the eggcrate. Very efficient protein skimming is also
recommended. Anthony's book should be of great help in this venture. Do
continue reading/learning on this subject, learn as much as you can
before starting this venture.> Thanks, <You're welcome. James

Frag tank 2/5/08 Hello Crew, Hope all is well with
you. I have recently studied several books such as Anthony Calfo's book
on Coral Propagation, and Bob Fenner's Conscientious Aquarist and have
been overwhelmed and awestruck with the massive information. <Is an
involved, involving hobby interest eh?> These books have been
extremely worthwhile investments, and I have got an insatiable desire to
start a small frag tank in our spare bedroom also known as the fish
stuff room. <Jumping right ahead!> I have a 75 gallon aquarium and
I would like to run my ideas by you for your input. I will build a egg
crate rack with one 12 inch shelf at 12 inches below the waters surface
and one 6 inch shelf 4-6 inches below the waters surface. Lighting will
be natural sunlight through the window for about 5 hours a day and
supplemented with T5HO (4x54) for about 5-6 hours a day. The targeted
species of propagation would be primarily softies such as Zoas,
Mushrooms, Sinularia, Leathers, and Xenias with some interest in less
light demanding LPS. <Mmm, ahhhhh, I am encouraging you to read a bit
more re which to cut up first... not to mix... to rinse thoroughly
before placing...> My ideas for filtration are protein skimmers
(HOB), <Mmm, a sump would be better... for quite a few reasons...
flexibility...> a container or even 2, approximately 16 inches x 12
inches x 6 inches filled with sand and placed on the bare bottom of the
tank. <I'd place this material in the sump...> This would be for
the benefit of DSB and also cleaning issues with bare bottom. <What
if pests become an issue? easier to find, isolate them...> I will
place 20- 25 lbs of live rock for biological filtration in the tank.
<This too...> I want to utilize a Mag 12 pump in the tank with a
manifold placed around the rim "Calfo style". I don't want to utilize a
sump with overflows on this tank and don't feel confident in glass
drilling. <Not hard to do, have someone do for you... even the
manufacturer...> I will utilize a refugium above the tank <Oh!
Good> and allow water to gravity feed down to the tank for nutrient
importation and exportation. Do you think this will work? If not where
should I tweak this plan? Thanks for your time, Wade <This system
can be made to work... but is not categorically what I would devise...
Perhaps a bit more reading and reflection. Please start here:

above. Bob Fenner>
Propagation Setup, Cnid. 2/1/08 I am thinking of
setting up a small propagation tank using a 20 gallon long aquarium. My
plan is to drill the bottom and have an overflow down into a 20 gallon
sump/refugium. I am thinking of propagating mostly soft corals
(Nephthea, Capnella), Zoanthids, and mushrooms. <Mmm, okay... best
to do/use this small volume for just one of the three groups at a given
time...> My first question is how much improvement would I get from
having an upstream refugium vs. an in the sump refugium? <Mmm, about
the same> I would have the refugium set up on a deep sand bed plenum
and fill it with Chaeto algae. Furthermore, I would not use a filter
screen on the return pump so hopefully all the copepods/amphipods will
make it into the tank. <Mmm, the screen won't hinder their passing
here... it's to prevent other, larger materials from damaging or
clogging the impeller> This is how my 75 gallon reef is setup and
I've had good results for over a year now. I was thinking of using a 600
GPH pump to run the sump and two 300 GPH powerheads with rotator
deflectors in the display tank for additional circulation. Is this too
much flow and if so what would your recommendations be? <Posted on
WWM... see Circulation... and Systems and Propagation/Reproduction FAQs
files for the Cnid. groups listed> As for lighting, I was thinking of
using 2 T5's at 10000K and actinic with a total output of 48 watts. I
specifically chose the 20 long for its shallow depth but with a decent
size length for holding multiple specimens. Will the T5's be a good
amount of light for my intentions? <Yes> Lastly, for feeding I
was thinking of offering small amounts of Cyclop-eeze, oyster eggs, and
liquid coral food every other day with no mechanical filter present. On
the alternating day running the system with a mechanical filter to clean
out whatever is left in the water. Does this seem like a good feeding
regimen or is there a more efficient/better way of doing it? Thanks so
much for your help. <For a home-hobbyist attempt this should work out
fine. Bob Fenner>
Frag tank... Mechanicals, reading – 1/26/08 Hello there
I was interested in setting up a tank to use as a frag tank mostly
softies maybe a couple of LPSs and sps corals also . I have a tank spare
tank I bought of my boos at the pet store I work at. <Spell
checker...> The dimensions are as followed it is 60 inches long (5
feet) 18 inches (1.5 feet) wide and 12 inches deep(1 foot) deep . <A
good size, shape> It was custom made by oceanic . It is drilled in
four places all along the back . It also has a glass brace in the middle
. I consider my self very lucky that I got that tank and another tank of
around 50-60 gallons for 80 bucks . What I was wondering was your
thoughts on lighting and filter choice if my budget is around 200 to
around 400 dollars. Any other input would be greatly appreciated. Tom
von Bargen <All posted... Read here:

Propagation" book. Bob Fenner>
Was: Cherub Angelfish Question... Now Skimmer op., Frag tank set-up
Good day Bob, <Eric> Thank you for the quick response. I really
appreciate it. I have another question. Well, actually, two
questions. One is related to my skimmer. It has been up and running
continuously for about 3 weeks, and is still creating about 1-2 cups of
skimmate per day, however it's a lighter green to light-medium shade
brown color. It's not the "dark coffee" colored, thick skimmate that I
have been expecting. I have adjusted the height so that the skimmer cup
is about as high as it can go (the O-ring is as low as it can go on said
cup) and it's still producing the above colored skimmate. I don't
think I'm too low on the stocking level.. Is this normal? I know that
the skimmate production is different for different folks as well... Do
you have any suggestions? <This may be about all that the given
make/model skimmer can do with the present conditions in your tank...
There are means to change this... by adding ozone for instance... But I
would not be concerned> The second question is in regard to a "Frag
Tank". I have been thinking of setting up a 20 Gallon Long tank to have
some "easy" polyps and (mainly LPS) corals. I am in the exciting
planning stage, and here's what I have so far: -Power Compact
Lighting, somewhere between 80-100 watts, 60 (or so) 10,000K and (20 or
so) watts 6,700K (or 20 watts Actinic). -An over sized filter (rated
for 30-50 gallon tank) -An extra powerhead with rotating deflector.
(Flow will be toward the filter. One will be on left side of the tank,
the other will be on the right hand side) -plastic egg crating or
similar, set up on different levels ( like a few stairs.. from West to
East) so that I can have 2 or 3 different heights for acclimation and
differing light requirements. -a few pounds of live rock set under
the egg crating. - There won't be any fish (...If you think it will
be "better" I could add a small goby or similar) Questions: How does
the above sound so far? Should I add a sand bed? Would a 3-5 inch plenum
type help here, or should I leave this out.. Maybe have a 1 inch sand
bed if I decide to add some inverts? If yes, I will add part live sand
and part "non live" sand to the mix. <Okay, I would and no... Please
read here: http://wetwebmedia.com/corlpropfaqs.htm and the linked
files above. Have you seen Anthony Calfo's (new 2d. ed.) Coral
Propagation book?> Also, I am a bit concerned with the nitrification
process, especially in the beginning, and will be reading more about
that in the meantime. I am familiar with setting up a FOWLR or Fish-Only
set up in this regard, but not a "coral/polyp only tank, with some
inverts" <Best to fast-start with water, substrate from an
established system, use make-up water from there...> Once again,
Thank You for the Help! Eric <Welcome. Bob Fenner>
Attaching Coral to Live Rock – 12/9/07 Hello Everyone, <Hello,
Brenda here tonight!> I'm sorry if this has been covered. <Not a
problem!> I searched but did not come up with the answer. Any way,
I'm waiting for my tank to cycle, so I'm looking for info on coral
frags. <This is an exciting time!> My rock does not have any flat
areas. Will they still attach to an uneven surface? <Oh yes! It may
possibly need some assistance (depending on the coral), super glue gel,
fishing line, toothpicks, bridal veil to name a few. Many corals come
attached to rock rubble, and just need to be placed in a crevice. What
corals are you planning to keep? I have propagated many corals and may
be able to give you more in-depth detail knowing the coral. Be careful
when purchasing newly propagated coral. These generally need to go
through a recovery period before adding the stress of a new/different
environment.> The rock is very porous. It has a lot of craters.
<Sounds like excellent live rock!> If this has been covered I'm
sorry. <I’m not finding a whole lot of information here myself. You
can try reading here: http://www.wetwebmedia.com/corlplcfaqs.htm and
here: http://www.wetwebmedia.com/corlpropfaq2.htm You may also want to
Google “coral propagation” for more information.> I know you are very
busy. Thanks for the help. Should I try to find rock with smooth
surface? <No, what you have is best. Just be sure that your tank is
ready before adding coral and know the care required for each. Since it
is still cycling, it will be some time before it is ready. Until then
continue doing what you are doing by reading and asking questions. Good
luck to you! Brenda>
Re: Attaching Coral to Live Rock, Zoanthid Toxins and Safety – 12/10/07
Brenda, Thank you for the info!! <You’re welcome!> I was
thinking of starting with some Zoanthids, and go from there. I figured I
would start with these they seem to be hardy enough for my skill level.
As you know they will add lots of color to my tank. <Yes, you have a
lot of selection here. I have worked with and propagated Zoanthids many
times. Let me give you a quick run down on Zoanthid safety. As with all
coral, when handling you should wear gloves. However, with Zoanthids it
is a must to use eye protection, a complete face shield is best.
Zoanthids are extremely toxic, and can be deadly in extreme cases to
humans and their furry friends. I am aware of several cases where this
coral has released toxins by squirting someone in the eye or mouth, so
you will want to keep your mouth closed if not using a full face shield.
Keep pets and children away while you are working with these. Disinfect
your work area, and any tools used when you are finished. Some important
links to read: http://www.cbwinfo.com/Biological/Toxins/Palytoxin.html

http://reefcentral.com/forums/showthread.php?s=&threadid=158663&perpage=10&pagenumber=1
http://www.wetwebmedia.com/zoanthidreprfaqs.htm If you decide to
propagate these, it is best to remove a portion of the rock underneath
the coral. This can be done using a chisel or even a razor blade. Then
use super glue gel to attach to another rock, or frag plug.> Thanks
again for the info, and keep up the good work, your services are
invaluable and always appreciated. <You are welcome! Thank you! It is
always good to hear we are appreciated! Good luck to you! Brenda>
Re: MACNA & Frag Exchange, StevenP 8/15/07 Yeah
Mac, it is official now. Frag Exchange is not going to be an
exhibitor at MACNA XIX, so if you can, get one of the WWM passes.
In case you were wondering, I have long hated that the coral
propagation workshops fragment freshly imported corals. It is simply
poor husbandry and contrary to what Eric, Anthony, and I all
recommend. But up until now, I could do nothing about it other than
not do the workshops. But this year, we made the decision to only
fragment corals that had been held for 1-2 months prior to the show.
I let John know this back in early May and he agreed to the terms.
MACNA XIX would give Frag Exchange a quad booth, four 10' by 10'
booths, with 5 full show passes provided he could obtain
corals ahead of time. In the end, he failed to live up to his end
and we felt we had no other choice than to go with plan B and
leave Frag Exchange out.
Re: MACNA & Frag Exchange , MacL
8/15/07 Hey Steven and Anthony and Eric and Bob, I
included you all in this email since Stephen said that having corals
that have been kept for a while before they are used was a joint
decision recommended by all of you. <Not anything to do with me>
I totally understand why you would dislike fragging freshly imported
corals. They have been stressed in various ways by their
importation and the changes that they have gone through and then
they come in to be fragged. But my question for you is, isn't that
the reason to frag corals to begin with? <In part, yes> Yes
people frag their friends coral that is in great shape but more
often they want a piece of the coral that is dying and want to try
to save it. In our demonstrations, we take the dregs of the corals
that have been shipped. We ask for corals that are stressed and
in poor condition to do our demonstrations with. We talk to the
people and we tell them these corals have been severely stressed. We
are trying to take corals that would for the most part be disposed
of anyway from these distributors and put them to good use and in a
lot of circumstances SAVE the coral or a part of the coral. I do
think its a lovely idea to bring in corals from the local clubbers
and we usually do have some of these. I recognize that when they do
the demonstrations that you guys perhaps would prefer to use corals
that look nicer but I know Anthony always mentions that he uses
fragging to assist in saving the coral. In fact, I believe Anthony
prefers damaged corals. I know that sometimes these corals look very
bad and are very badly stressed but many corals go on to survive and
thrive from these shows. I personally have a gorgonian that is from
the very first show that frag did so I know for a fact that they do
survive. I had planned to bring a frag of this coral and frag it at
this show. Additionally, our coral sponsors for the show are very
generous people and have been kind enough to let us have corals for
both IMAC and MACNA but asking for corals without a gap in time
between our requests to me seems to be abusing the generosity of a
group who is giving us something. It was mentioned Steven that you
had space in your greenhouse to keep the corals should they have
been donated to us early as you requested but I also worried that
that could cause additional problems and suggestions of impropriety
with the corals. For instance, what happens if they ship 25 corals
and only 19 survive to make it to the show. What kind of
documentation would be necessary to provide proof of what happened
to the corals. In the past I would have said that only your word
would suffice but after past circumstances I don't think that would
suffice anymore. <Certainly seems a "Catch 22"> Additionally
you have the complications of what to do now with the frags that you
all will be fragging. What will you do with them? Will the club give
them out?? Will the club "store" them? That's where having the
corals that are not in the best conditions come into play as well.
The vendors cannot see them as competition to what they are selling
because they are corals that are damaged and we are essentially
trying to "safe" them. <Good point> I do want to point out
that our philosophy has always been to save the reefs and that at
any time if we thought that we were doing damage to the reefs we
would stop fragging period but its our philosophy that by teaching
these people how to frag and by letting them have hands on
experience at the booth that we are giving them something that they
can't get anywhere else. I was disappointed at IMAC that more people
didn't get that experience but at the last MACNA we reached out to a
tremendous amount of people and let them have hands on fragging
experience. This is something they do not get from just watching a
fragging demonstration and something that FRAG can give them. If you
look on frag you will see a connection to pictures with a
demonstration of one person who had never fragged before and when he
left he became comfortable with it. Once again the corals that get
fragged on the first day would be put in tanks with others. There
isn't really any other way around this but we have done everything
we can to prevent problems by using as many methods as possible to
keep the tanks clean including doing multiple water changes, diatom
filtration, and using ozone.? I also want to mention the support
that frag has always given to all of you. I realize that while
we may not have the most sponsors or the most hits of any of the
sites there are always people on the site and looking at information
on the site from searches on Google and other search engines.
Our presence is mainly at the shows and we need to keep going to the
shows to keep alive as you all well know. I don't know what plan B
is but it has to be hurtful to frag and the many people who have
supported MACNA and IMAC and you gentleman over the years. I would
really like you to reconsider this decision Steven. I do understand
the reasons why you have made them but I hope you have come to know
more why I personally objected to storing the corals before hand and
why I think it is essential that frag exchange be at the show.
Whether it is represented by me personally or not. As you know, I
have other interests along with Frag. Thanks Mac <Mac Lewis

Re: MACNA & Frag Exchange, EricB's go 8/15/07
Dear all: Since this is my first foray into this ongoing
discussion, I will be brief. I have gotten to the point where I
am generally against all commercial wild collection of corals for
aquariums, period. <Unrealistic... what will indigenous peoples
do with their resource if this "higher and better use" cannot be
made of/with it? Cement? Building material? Dynamite fishing?...
think> I am even against Mariculture at this point until
standards are set to avoid the pest species now being introduced by
Mariculture operations, <Unrealistic as well... who is going to
produce, enforce such standards? Who is going to pay for it?>
although I am hopeful an upcoming workshop may help address those
issues. And, I am against frag trading by clubs without
quarantine and proper post fragmenting husbandry for the passing of
pest species and the potential of non-native and invasive
introductions by the many coastal dwelling aquarists of the world.
<...> Ethically, I do like to save damaged corals, especially
from other aquarists who are having tank problems, but I am less
assured that the average aquarist is able to save a stressed or
damaged coral. I am unsure of the survival of fragments we create
since there is no post monitoring period, and we don't take our own
frags home to see if it is the post fragmenting conditions or the
aquarist who takes home the frags that results in any mortality. I
know when I frag my own corals they don't die. I know when I try
to save a stressed wild coral, it might make it and it might not. I
can even say that for healthy wild corals. But those sick and
healthy wild corals are then replaced by more, and frankly it just
sits wrong with me. <Perhaps another interest... like human birth
control?> And, let's face reality here. The aquarium hobby isn't
saving reefs in any way shape of form no matter how much talk there
is of our concern. Concern and action seem to be Kapela <<? RMF>>
and always have been. <Mmm, I/we disagree... the long term
effects of acquaintance, knowledge of the living world protect it
more than any other activity... Is this/the "cost" worth it? I
believe so> I did not know the terms Steve and Anthony suggested
for this MACNA, until now, but fully support them and think their
suggestions are, as mentioned, long overdue and well thought out. I
resent any implications that Steven would be involved with
impropriety of gifted corals. We have more corals than we know what
to do with - I could give away a tank full and never notice they
were gone - and the novelty of having this coral or that coral - and
I think I speak for all of us - has long ago ceased to be a
temptation as it is for so many hobbyists. I dare say we have had or
kept just about every species available and could get them easily,
if not for free, if we desired. In terms of the support given by
sponsors or vendors, I also really don't have any interest in their
financial success of failure though always appreciate the generosity
of others as we have so generously donated our time and effort for
literally two decades now. I appreciated being able to help Frag
with demonstrations and by their hospitality at events. In terms of
personal gain to us, I have a few T-shirts and some conversation for
a few hours a year, so it is not particularly important to me either
way. My main concern is that the corals entrusted to us survive and
all the rest is virtually immaterial. Steven, Anthony and MACNA XIX
seem to have attempted to address this concern and I stand by their
decision. Eric Borneman <Bob Fenner>
Re: MACNA & Frag Exchange, MacL responds 8/15/07
Well since I apparently have opened a can of worms here. I can only
speak to these things from MY personal experiences. Corals I have
fragged, responses I have seen, people that we see at the shows. And
once again let me point out this is NOT my website and I cannot
speak for anyone from there besides myself. I personally value all
that you all have done for Frag both for myself and for the website.
I have had much success with fragging corals and sending them home
and yes I have fragged corals straight out of the box both at the
shows and at stores. I do see the value of having the corals settled
but I also see where they would be disturbed by moving them to the
shows as well. <Mmm, the thought here is likely to promote better
circumstances for the candidate... and business for the folks
involved> As for any impropriety I do NOT think that Steven would
ever do anything wrong. But I know you wouldn't as well Eric and I
personally shut several people up at IMAC that started to tell me
crap, My point being that there are people who do not know or
respect you like I do. At this point it doesn't matter as Anthony
said its over and done. I am sorry if I have offended anyone, I just
for once felt my opinion should be known. For the less than two
cents its worth. Mac <Thank you for sharing. BobF>
Re: MACNA, Fragexch., advocating more gov't unrealistically...
8/15/07 Hi Bob: <Howdy Eric> Not arguing the realism of
your post. <Realism?> My remarks are personal decisions and
controlling behavior and things of which are in the realm of
control. <For yourself I take it> I can't stop, nor have
connections to stop, all major threats to coral reefs. I drive a car
but wouldn't if there were viable options. I opt not to have a lawn
and to eat organic and no meat. Will it solve global warming? No.
<But does help> Unrealistic? Yes. But a journey begins with a
single step. To me, everything makes a difference and arguing that
"our contribution" won't make it right is why things are so f'ed up
in the first place. E <Thanks for your further input. BobF> |
Conservatory Frag Tank...How To Control The Heat? – 08/06/07 Hi
There, <<Hello Karl>> I wonder if you could help or offer any
advice on a system that I am setting up? <<I’m happy to try>> I
want to setup a 55g frag tank (to grow pulsing Xenia, Metallic Green
Xenia (Star Polyps), various other Zoanthids) in my conservatory (not
sure if these go under the same name in the US - it is like a glass
house with plastic roof built onto your house). <<Ah yes, I am
familiar with these/this term (lived in Ipswich for 3 ½ years). The U.S
equivalent is called a three-season room...or as they often call them
here in the South East, a “Florida” room (even though it may not
actually be located “in” Florida)>> Anyway, the conservatory does not
get full sun, only afternoon sun. I would like to utilize this natural
sunlight, as well as supplement this with a 250w 14k metal halide lamp
(would you suggest this or a lower Kelvin globe as I am aiming for this
to be a grow out tank). <<This is doable...and if “growth” is what
you are after I recommend a Kelvin temperature closer to natural
sunlight (5500K – 6500K)>> My question is this... Even though I get
only afternoon sun (and I live in chilly old England) <<I do recall!
[grin]>> the temperatures still soar once the suns starts coming
through. <<Mmm, yes...I imagine with all those transparent
walls/ceiling the solar gain would be quite intense, even at your
latitude>> I am planning for this system to be open top, with 1 or 2
large fans blowing across the water. I also plan to extract heat from
the metal halide out of the window with an inline extractor fan. Do you
have any ideas on how else I can keep the temperature down during summer
(winter is not a problem)? I really cannot afford to air-condition the
entire room, or purchase a chiller. <<Hmm... The extractor fan will
also likely pull some ambient room heat and may prove to be enough. You
could also install a louvered ventilation fan in one of the windows that
operates on a thermostat to pull excess heat from the room...much like
those used in greenhouses to control temperature. Visiting a greenhouse
may give you other ideas such as installing window or roof vents that
can either be opened manually or controlled with a thermostat to open up
when the temperature rises to help vent hot air>> Will evaporative
cooling (automatic top-off using an Osmolator and Kalkwasser) <<I
love those Tunze Osmolator top-off units>> be enough to keep temps
within the acceptable range? <<Only testing will tell...but is worth
a try. Evaporative cooling can be quite effective>> Any advice you
could offer me would be much appreciated. <<I hope I’ve given you a
few things to consider/investigate>> I have had a great deal of
success with my nano and now that things are getting a bit crowded, wish
to grow these frags out to sell/trade. <<Quite common>> Sadly, my
conservatory is the only space I have available to setup a frag
system... :O( Any advice would be much appreciated! Best Regards,
Karl <<Good luck with your venture. EricR>>
Attending a Frag Swap...Who Will/How Do I Store My frags? - 04/18/07
Hey guys and girls, <<Howdy Greg>> I plan on attending a frag
swap at the end of June. <<Ah yes...that's the coral conference
being held by Foster&Smith isn't it?>> The frag swap is 10 1/2 hours
away. <<Driving then?>> We will be going on a Saturday and
Sunday and plan on coming back on a Monday (early). My question is what
to do with the corals that we purchase Saturday and Sunday. <<Mmm,
this will depend on how the vendors/traders are "set up." If they are
equipped with "running" systems and are there for the duration of the
swap-meet then ideally they would mark and hold your purchases to be
bagged the morning of departure (much like the vendors at the MACNA
conferences). If not, then you will need to bring storage/transport
containers as well as a means to perform water changes/re-bagging>>
Would it be possible to bring water out of my tank for a 10 or
20 gallon tank with a powerhead and a CF to store the corals until we
bag them before we go home. <<This would work (if the place you will
be staying has no objections)...do be sure to "acclimate" the corals to
this holding tank>> Or should I just mix up the water when we get
there??? <<I suppose you could do that, but I would prefer water
that is "matured" as this will be less aggressive/stressful on the
corals. If hauling that much water is a problem, you could just bring a
few gallons of the tank water and mix-up the rest at your
destination...then mix this with the matured water you brought with
you. I recommend you do this as soon as you arrive and get the holding
tank up and running before venturing out to the frag swap>> Any
other options would be greatly appreciated. <<Do contact the
person/agency sponsoring the swap and get their feedback as well...there
may well be some type of consideration already in effect>> I plan on
asking the vendors if they will keep the corals until Sunday but if this
is not possible I want to do the best thing for survival! <<Indeed>>
Thanks, Greg <<Enjoy the meet. EricR>>
Propagation System in My Garage... – 03/03/07 Hey WWM,
<<Hey Erik!>> I've often referred to your site and expertise
when I need a question answered about one of my tanks, and through
experience I've found that you guys know your stuff! <<Ah, thank
you…a diverse and knowledgeable assemblage here for sure>>
Usually I can find someone else has had the same problem as me and
use your answer for that, but in this case, I think I need some
personalized help. <<I’m here to assist…>> I am planning on
setting up a propagation/holding system in the garage and am having
some doubts about my plumbing knowledge (I've attached a picture of
my "plan" )... <<I see it…and for future reference, please
resize images to a few hundred Kb at most>> Each tank on top is
about 55-gallons, and I have a 180-gal sump area. <<Ok>>
First off, from my sump there should be close to a 4 to 4 1/2 foot
head, straight up, no turns, one gate-valve, and one union.
<<Sounds fine>> I am planning on using either a Quiet-One 6000
or a Mag-Drive 18, which according to their chart should give me in
the neighborhood of 1200 to 1300 gph. Right? <<Sounds
about…yes>> Should I go bigger or is this adequate? <<Should
be adequate as is>> From my sump, water is pumped into tank 1
(top left), then I want to pipe it to tank 2 (bottom left), and into
tank 3 (bottom Right), and into tank 4 (top right), and finally in
tank 4 it drains back to my sump. <<I understand>> My
question here is: what size bulkhead should I use between the tanks?
<<A “pair” of 1.5” bulkheads or a single 2” bulkhead should suffice
with the water flow you are planning>> I was thinking a single
1.5" between tanks and then two 1.5" drains to the sump. <<Not
sure why you would think the other tanks would need fewer
throughputs than the one draining to the sump…but I would
“double-up” on all the tanks>> Will that work or do I need
larger bulkheads between the tanks? <<As stated>> Does it
even matter? <<Oh yes! Make like easier for yourself and think
“super size me!” re these throughputs>> For additional flow in
the tanks, I plan on using powerheads. <<Hmm…with 1200-1300 gph
of flow going through these 55g tanks I think you’ll likely find the
powerheads as unnecessary>> I think I'll figure it out, but I
would appreciate any help you can throw my way. <<Happy to
provide my opinion>> Thanks a lot. Erik Hunter Long Time

Frag tank lighting 10/2/06 Hello WWM crew I
have a 20 gal SPS frag grow out tank I am setting up plumbed into my
main system. I have a 2X55 watt 6700k fixture I have considered using
(the frags will be on a rack 8-10" below the water surface). Do you
think this will work or should I go to option #2 which would be a 150
watt HQI Iwaki 6500k. Thank you very much for your opinion and all the
information you have on you awesome site. Scott <I'd use the
fluorescent... and make the grow out tank water depth adjustable... an
inch or two above the frags is ideal. Bob Fenner> Re: Custom
Frag Tank lighting -- a follow-up - 1/18/07 Thank you for your
quick response. <No problems, my friend. I enjoy feeling
helpful.> Okay, I'm going to go back to a standard aquarium as a
sump so I can put in the refuge for the corals but I have a follow up in
regards to the lighting. I would rather have MH than VHO, just my
preference. <Fair enough, we all have our preferences. VHO would not
be my choice either, in fact if I were to endorse any specific
technology, it would likely be T5-HO, due to their smaller size, lower
heat, longer bulb life, and good penetration, but I digress...> So
if I went with MH lighting, being that that my tank is 3 ft wide, would
something like a 2x250 HQI with PC actinic 48"x15"x3" centered over the
tank give enough lighting to the edges. Or is their a different set-up
you would recommend. <This sounds good to me, my friend. I think it
will serve you well. -JustinN> Thanks again. Selling to
wholesalers 9/26/06 I would like to propagate a fast
growing coral species to sell to wholesalers. If I were to reliably
produce a relatively high volume of a single species each month would
there be a market for this product? <Possibly> If so, is there a
comprehensive list of wholesalers to contact about their interest in
buying from a single species supplier. <Mmm, not as far as I've ever
seen... many can be found through searching about in "Buyer's Guides"...
produced by industry mag.s... Phone directories, you can peruse at
large/r libraries... searching the Net... e.g. organizations members
lists like OFI...> Also, is there an industry standard as far as
contacting wholesalers regarding this situation (i.e., letter, phone
call). <Good question... Best to call them, ask who makes such
decisions, what they might be possibly interested in some/several months
down the line... what they might be willing to pay (FOB/landed) for
such... But, allow me to cut to the proverbial chase here and suggest
you sell a mix of such possible cnidarians more locally... likely the
fish stores you can drive to will take about all you can realistically
produce... The nature of the trade is such that guessing "what will be
hot" and the margins being so small to non-existent dealing through
wholesalers, that you will first be most likely selling to LFSs, and
second to this, only/either to end-users/consumers... Not to both. BobF>
Thank you, Amy SPS collection business
8/21/06 Dear Bob and crew, <Alan> I'm thinking of
starting an exclusive Acropora collecting business to supply to the
trade. I only wish to collect Acroporas from the wild by fragging a few
branches from a colony and gluing them unto rocks for sale in order to
minimize impact on ecosystem. <Mmm... can't really be done this
way... need to collect colonies, keep them in captive conditions... some
time (months) later frag them... Too hard to make the transition
otherwise> I suppose this will generate faster returns rather than
having an aquaculture facility which requires more overhead cost and
time. <...> Do you think this is viable in the long run?
<Nope> Any words of wisdom? Thanks a lot. Best regards, Lee
<Keep studying, dreaming, planning... Bob Fenner> Brain (coral)
frags, xenia repro. - 04/19/06 Hello, I was
wondering if it was possible, or how to, frag a brain coral. <Can be
scored, cut with a chisel et al., but best cut with a power tool that is
securely mounted... a "wet-saw" for cutting tile, or a band-saw is most
often employed here> Also, once xenia starts growing all over the
same rock, is it normal for it to sort of grow taller as it fights for
position, the last time it started getting taller was because a bulb had
burned out and they needed more light, I think. <Happens> I
checked and all the bulbs are good and since the last burn out I have
even got a new lighting system that adds about 55 watts more, they are
reproducing like crazy, and fully opened all day and most of the night,
so I don't think they are unhappy, but when I first got them they were
shorter. Is it because there is almost 10x the amount now versus when I
bought them? Thank you for your time. <Maybe. Please see WWM re
Cnidarian culture:

Holding system manufacturers? - 04/11/2006 Hello Bob,
Miguel from Fraggle Reef here, you guys have helped me out on several
occasions, and I was wondering if you had any information on companies
in the Los Angeles area or anywhere nearby that manufacture
retail/wholesale holding systems? <Mmm, yes> I know
of rk2 systems, but Chris is apparently in the Colorado office, and I
was looking to get the ball rolling immediately, and wanted to
compare prices and services. I was planning on making it a centralized
system, in a relatively small area, holding system space for corals is
17'x18', so I wanted maximization of that space, and would put it
together myself, all I needed was the actual raceways manufactured,
along with the rk2 style smaller holding systems for inverts. Thanks
much for your time, it's very much appreciated, thanks! Sincerely,
Miguel Fraggle Reef <Well, the Krechter's are very good at what
they do, and friends... but their products are indeed pricey. Another
couple of choices worth chatting with till you decide are Alan Lem at
Advanced Aqua Tanks and Craig DeWalt at SeaClear/Tradewind/CASCO in
Cerritos... A note also re checking around to see if some folks have
some gear that they might want to sell used. I would call the large
livestock wholesalers and ask their owners re this... Totes, tanks, even
mechanicals and controllers can be had for much less... and really...
does it matter much if they're scratched up a bit? Not to me. Now, if
"price is no object"... Bob Fenner> Re: Holding system
manufacturers? - 04/11/2006 Hello Bob, Very true,
I'd rather have a scratched up el cheapo tank than pay a premium for the
same tank unscratched, I'll contact some of the wholesalers and see
if they have extra gear, thanks much for the tip. <Certainly
welcome. Works to all's advantage for you to have/use...> In the
meantime I'll also contact Alan Lem and Craig DeWalt to get some pricing
on the raceways, thanks again for your time Sincerely, Miguel

Fenner> Please lend advice to a budding coral
farmer 3/24/06 Hi Mr. Fenner, <Niki>
I know you are so busy, thank you for all you do. My name is Niki, I
have actually spoken with you before on a couple of occasions. I have
been working for a retail saltwater store for a while, and recently I
got 15,000 to start my own business. not a whole lot, I know. My dream
is to have a little place to grow coral and then sell on the Internet.
<A worthy project> I have good relationships with a lot of agents at
ERI, ORA, etc. due to working in the industry for a while. I am 23, but
I am fairly confident in my knowledge. I would love to have
something like reefer madness or ultimatefrags. I love the idea of
Internet and not retail. Do you think it could be done with 15,000, a
20ft x 30ft room and a lot of grit and determination? :) and passion for
he hobby? <Yes. Of a certainty> I would love to hear any input
at all. If you think it would be a pipe dream or if I would even make
any money at all. <Could be made to be profitable... with careful
planning, the use of as many "shortcuts" as you can find/make...
Particularly issues of energy use/consumption, scheduling your
time/discipline, knowing and developing your market niche... E.g., what
species will you culture? How will you find, contact your potential
buyers? How to ship, process payments?> I am going to go to bar
tending school and work that as a second job so any money that the farm
pulls can go right back into it. I have Mr. Calfo's book, it's been a
big help. thank you in advance for even reading this.
Sincerely, Niki Englerth <Much to consider here. One very
worthwhile and telling experience is to "do a business plan" with
layout, costs to build, operate your proposed farm... AND a spread sheet
with time frame, showing what you expect to sell, the subsequent
profit... Go into this with your eyes open Niki... can be done, but...
important to realize the "opportunity costs"... that is, what you might
otherwise do with the same resource/s... particularly your time. Think
on this well, and feel free to write back. Bob Fenner>
Mounting M. capricornis Frags - 11/18/05 WWM Crew, <<Kevin>>
I received a small capricornis frag today, and I am inquiring in to the
best way to attach the frag to a small rock for placement in my tank. Is
superglue necessary or are there other possible means. <<Superglue is
the best way in my opinion. Very easy to do...gently blot the back of
the frag dry with a paper towel, place some superglue (gel) on the back
and press to the rock...a quick dip in the tank water while holding the
frag in place will speed curing. Once the glue starts to set (usually
about 15 seconds), place the frag where it will receive good water flow
and adequate light and it will begin to encrust/grow in no time at
all.>> Thanks. Kevin <<Regards, EricR>>
