Carbon placement
Hello to all. I have a question about the use of carbon filtration. We
have a 40 gal. tank and currently use the Amiracle 150 Wet/Dry Filter and the
AquaC Remora hang-on skimmer. I do 2-3 water changes of 4 gal. each a
week. I
read all the postings I could find on the site about this before bothering you
with a question, so I know the recommendation appears to be 1x month use of
carbon filtration. Right now I have Fluval carbon filter pads just laying on
top of the biomedia, directly underneath the plastic diffusion plate (which has
the filter pad on it). I can't think of another place to have it that would put
it in the direct flow of water. << That would be fine. >> My preference would be
to use the TMC High Retentive Activated Carbon product in a filter bag, but I
definitely wouldn't know where to put that except the sump, which obviously
wouldn't really be in a flow. Any thoughts? << Yep, anywhere is better than
nowhere. I'd put it there and just leaveCarbonFAQ2e it there all the time. But high flow
is certainly best. >> Thanks for all the help. I get information from you site
all the time. You guys are the best.

Carbon placement
Dear Bob and Crew,
I have a 90 gallon reef with a wet/dry and newly added refugium with a DSB. I thought I would start using some carbon in my system. Do you think it would be a better idea to place a bag of carbon in the top of the drip tray or should I use a mechanical filter (Hot Magnum) with carbon in it for an
occasional overnight cleaning? Thanks!
<Mmm, would work fine in either placement... I'd likely go with the canister filter for the added circulation and mechanical filtration. Bob Fenner>
Anemone/ Turtle Weed tank, GAC use, Chlorodesmis comp. 2/27/07
I tried what you suggested, but despite the searches I still couldn't find
anything relevant. Can you please just give me a direct answer or at least refer
me to a specific FAQ?
Thanks in Advance,
CCS
<Mmm, perhaps more of a specific response... There is some value in the use of
activated carbon in a setting as you propose... some for absorption, more for an
adjunct to bio-filtration... I would use "a few ounces" of GAC in a Dacron bag
(that can be easily re-used), changed out once a month or so... Sandwich this
twixt some mechanical filter media (to keep off detritus)... And the Chlorophyte
genus Chlorodesmis ranks low in relative allelopathogenic properties... perhaps
a 3 out of 10... I would not be concerned here with potential effects with
Catalaphyllia... BobF>
Chemical filtration placement question for
a hang-on refugium 6/24/07
Good evening,
I first want to thank you for your site and all the great information, I don't
know if I could have survived this hobby without it. My question is as follows:
When adding chemical filtration, specifically Chemi-pure, where should I place
it in a CPR hang on refugium/ skimmer unit. I just purchased Chemi-pure and had
it in the compartment after the skimmer and now it seems that the Caulerpa in
the refugium is turning white and breaking apart. I thought about putting it in
front of the return portion of the unit,
<Mmm>
but I am fearful that the copepods and stuff that is supposed to leak into the
main tank from the refugium wont.
<Not to worry re this...>
The only filtration I currently have is live rock and the CPR and would love to
add the Chemical filtration, but the only option I have is to place it in the
refugium. I used to use carbon in my Prizm and thought it really helped. I would
therefore like to continue with the added filtration with my new set-up.
Thank you in advance for all of your help!!
Cory
<Somewhere in the filter flow path, though not blocking same... toward the exit,
return, though most anywhere in this unit would be fine... I would only switch
such a product out once a month... using two would be best, leaving one in while
changing the oldest each interval. Bob Fenner>
Carbon in Prizm
Many thanks for your help so far. I wanted to know if I can put a small bag
of carbon in my Prizm skimmer. Will this effect skimming?
<Yes, probably for the worse.>
I know the skimmer is not the best but I bought it anyway do to only using it on
a 20gal.
<Will be fine for a 20 gallon tank.>
I already have a Fluval 204 for mechanical and filled with TBPC for bio
filtration. I have just removed all of my crushed coral except for about 1 inch
and I am going to add 20lbs of LR if I can get it past my wife. Shaun Nelson
<It would probably be easier/better to place carbon in the Fluval if you do
not already have it packed. I prefer to use Boyd's Chemi-Pure in canister
filters. If not, a simple hang-on filter is a cheap alternative. -Steven Pro>
Carbon
In your book "The Conscientious Marine Aquarist" you say it is
best to place chemical filtration media such as carbon in polyester bags and
arrange there placement in a pressurized water flow.
<And I would agree.>
You also say the worst is to just throw the bag and contents into the sump. If
all I have is an overflow box and a sump is it better to put it in the sump than
to not have any at all?
<You can probably rig something so that the overflow water is directed into
the carbon. Just do so such that if and when the carbon becomes clogged the
water can continue to drain down unobstructed. -Steven Pro>
- New Tank Set-up, Follow-up -
Thanks for the reply.
<My pleasure.>
With this setup, do I need to add any kind of carbon filtration, and if I do, how would I incorporate it into this system.
<You can... I did... is quite easy to just place a micron bag filled with carbon in the sump, leave there for a little while... couple of days.>
Thanks again.
Mitch
<Cheers, J -- >
