Green Hair Algae 11/26/11
<We require that people send files of no larger size than a
few hundred Kbytes. See WWM re Chlorodesmis. Bob Fenner>
For a almost 6 months we've been losing a battle to green
hair algae. Our 250 reef tank had been doing well until the back
of the glass was covered with hair algae. Not thinking/realizing
it was time to add more to our CUC, we scraped the back glass
ourselves and the hair algae attached to the rocks. We tried
manually cleaning the rocks but the few threads we missed clung
to new rocks and continued to grow. When I have browsed your
website, the closest algae to ours appears to be turtle weed.
I'm attaching
pictures to see if you could please help us identify our hair
algae. Our magnesium was low (1120) and our nitrates were at 10.
We are raising the magnesium and continuing to run carbon and
phosphate removers. We have added additional types of macro algae
to our refugium, changed our lights, reduced the light period of
our MH to only 6 hours but still have the VHOs on 4 hours prior
to the MH and 4 hours after the MH. We have also reduced feedings
and recently added snails (Astrea turbo snails). We had been
trying to use Mexican Turbos but hadn't had much luck with
them. No one wants to eat it and we can't seem to kill it.
Any type of ID help would be greatly appreciated. Thanks for your
help and guidance.

Re: Green Hair Algae 11/26/11
Here are the smaller images, I will check out Chlorodesmis.
Thanks
<Ahh; I/we thank you. The 50 Megs of space our email has was
past 76% full>

<Welcome... do consider a (remoted) DSB as well. BobF>
Re: Green Hair Algae 11/27/11
Thank you so much for your response. I'm really perplexed to
how we have turtle weed growing in our tank. Besides installing a
remote DSB are there any other suggestions you might add?
<Mmm, the usual trials for potential predators, other means of
nutrient deprivation... Read here:
http://www.wetwebmedia.com/marine/maintenance/maintindex.htm
scroll down to the Algae Control tray... BobF>
None of our fish will eat it but it seems like some of the Astrea
snails are working on it. I have ordered some Mexico Turbos to see
if they will help too. Any other suggestions? Thank you again. |

Algae Identification 10/20/11
Hi my tank is being plagued by this algae and I would like to
remove it from my tank.
-Jason Quan
<Is likely Neomeris... see WWM re. Bob Fenner>
|
|
|
Re: Algae Identification 10/20/11
I do not think its Neomeris since none have ever had white
stalks.
<Don't always...>
When removing them by hand they feel slimy.
<Many algae are... do you suspect this is a Cyanobacteria? See
WWM re, use a microscope and examine. B>
They look like long bubble algae but not clear, they are dark green
and not filled with fluid.

Bryopsis? 5/8/11
Hey crew,
I was wondering if this sounded like Bryopsis to you (that rhymed, but
oh well). I have a bunch of this green algae growing on my live sand,
and whenever I disturb it by displacing the sand, long strands of it
start floating around, still attached to a piece of sand at the base. I
wasn't sure if they were Bryopsis because the pictures I saw for
the most part looked something like
--->->->--->->->--->->-> or
---|-|-|---|-|-|---|-|-|.
What I have looks like -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-< .
<?>
It has the slightly thicker stem running up the middle with small hairs
(not sure what to call them, sorry) sticking out perpendicular from the
side at even intervals. Also, at the end it appears to fork off like a
snakes tongue.
Is this enough to get an idea without a picture?
<Not me, no>
Just really wondering because if it is Bryopsis I'll have to get a
Tuxedo Urchin temporarily I suppose. It keeps getting sucked up in the
powerhead when I dislodge it so I have had to clean it daily.
Thank you very much as always,
Sam
<Perhaps a bit more searching, reading, seeing some other
representative images. BobF>

Request your help to ID algae 1/26/11
Dear WWM:
<Chris>
I've noticed what seems to be some sort of macroalgae growing
in different spots on the live rock in my tank. I couldn't
find any pictures resembling it on either your site or in Julian
Sprung's "Algae" book. I've had Caulerpa
taxifolia and Valonia show up a couple times before, and it looks
nothing like that. From the attached photo, can you tell me what
it is, if it poses any detriment to the tank inhabitants (soft
and LPS corals), and if so, the best method of removal?
Chris
<Mmm, is this laminar (flat, blade-like), two-dimensional or
more "tubular" in cross section. Appears to be a Codium
sp. to me (great common name, "Dead Sailor's
Fingers"... can be easily excised close to the point of
attachment... but not terribly invasive, fast-growing. Put
another way, I'd leave, and enjoy it. Bob Fenner>

Re: Request your help to ID algae
1/26/11
Definitely "tubular" in shape. I searched Codium sp.
algae pics online...yes, looks just like that! Thanks so much for
your help.
<Glad to assist you, BobF> |

Algae hitchhiker ID: Acetabularia crenulata
Mermaid's Wineglass 7/26/2010
Check this out........I just spotted this in my fish only
tank.
<Cool!>
It has no live rock or substrate, or should I say it was started
with none!
<Looks like some crushed shells in any case.>
What is it, I assume a plant/algae of some kind.
<It is an algae, and a relatively rare one (in the pet
industry anyways).
It is Acetabularia crenulata, or commonly known as mermaid's
wineglass algae. A nice find!>
<You can read some about it here:

Xeniid & Algae I.D. & Compatibility
3/8/2010
Hi, Can you please tell me what these are? Scientific and common
names would be greatly appreciated. And is the algae a threat to
the Xeniid chemically?
<Please see here: http://wetwebmedia.com/xeniidarts.htm
and the ID FAQ linked above re the Pulsing Coral; and the
green... can't tell w/o microscopic photographs>
If the pics aren't clear enough, just let me know and I might
be able to send some that are a little better.
Thank you,
Greg

Unidentified Single Loop Tube, ID and growing
Rhodophytes sans essential nutrients 2/10/10
Dear Crew!
<Tom>
I am a hardcore believer in researching and not taking the easy
way out.
So believe me when I say I invested, not wasted, hours looking up
more information about the little critter I have attached a photo
of. First the facts I have a 75 gallon FOWLR tank with 80 lbs of
live rock and the following stock:
Niger Trigger (temporary until I feel his new home is well
establish enough
he's only two inches long).
Chocolate Chip Star (not my idea received as a gift/rescue).
Tiger Cowry (Same as above).
Twenty Hermits (Blue leg, red leg).
10 Nassarius Snails
10 Various other snails
Specs
Temp 75F
PH 8.1
Ammonia 0
Nitrite 0
Nitrate 0
Phosphate 0
Calcium 425
I have a AquaC Remora Pro Skimmer
And four stage UV filtration system
First, what can I do to make my red macro, both pictures
attached, grow?
<Need/s some/appreciable Phosphate and Nitrate among other
possibilities...
Whatever you're doing to absolutely exclude, remove these
needs to change>
It is turning clear and does not seem to be increasing in size at
all. Second I only have two of these green loopy thingies, which
I am sure is their proper name, should I removed them?
<Mmm, no... unless you're concerned re their
proliferation. Are types of bubble algae... See WWM re>
They are bright green and there does not seem to be any
tentacles, nets, fans etc., coming out in light or in the
dark.
I attempted to get the best picture but the largest is not even
pushing half an inch and they are almost transparent. Any help is
appreciated. I am very grateful for the wonderful resource your
site is to me consistently.
Thank you. Thomas Mathews Horne
<Welcome. Bob Fenner>
