What's This... Two of the
same pics of hair alga 8/21/07 <Greetings, Mich
here.> I found a lot of these living in my display tank. Are
they copepods? <Mmm, don't know. I think you inadvertently
attached two of the same pic, both of algae. If you resent,
hopefully we can ID.> Also what type of plant is this growing on
my live rock? <Mmm, might be Cladophora, a type of green hair
algae. If it were me/mine I would remove it before it gained a
foothold. Cheers,
Mich> |

| Marine Macro-Algae Identification Help
8/16/07 Hi WWM Crew, <Nicole> I hope you can help me
identify the algae growing in my nano reef. I had thought I saw a
picture somewhere on the wwm site but tried to find it again and
couldn't. I like it, but it grows fast so I keep hand removing
it so it doesn't take over and would really rather find
something that can live comfortable in my 12 gal. JBJ nano
(original line from when they first came out!) with my 3 clown
gobies (2 black, 1 green). I love watching the fish swim in and out
of it! If more pictures would help, let me know. I didn't want
the message to be too big. Any help in identifying this species
would be most appreciated! Nicole S. (p.s. if interested you can
see some of my tanks at www.flickr.com/photos/runesrule) <Thanks
for this. This looks like a species of Derbesia... but might be a
Bryopsis... or another Green... some folks consider these
"weeds"... but if kept not-too-out-of control... Bob
Fenner> |

Re: Marine Macro-Algae Identification Help --
08/17/07 Thanks for the reply. Here are some better pictures
with more detail. I don't really think Derbesia is the right
species. Bryopsis is much closer I think, but still didn't
find any species with the mini shaving brush branch look. Thanks
again! Nicole <... this looks much more like Caulerpa
paspaloides in the closer-up views. BobF>

Some odd hair algae ID? 5/10/07
Heya people! <Hi there Mark1> I'd like your thoughts on
this algae I've got growing in my 15g
setup. I've had this algae growing since I first set
up my reef tank 2 years ago doesn't seem to be very fast in
spreading, although seems to regrow very rapidly when ripped out.
<Yes, I too have had some of this algae in my tank.> Its very
tough and hard to rip out, and feels very strong. <Yes.> Any
ideas on what kind of algae this might me? <Is a green hair
algae, perhaps Cladophora or Bryopsis.> And how I could get rid
of it perhaps? <Manual remove is a good place to start, perhaps
even chiseling off some of the rock, keeping water quality high,
much more here and the related links in blue: http://www.wetwebmedia.com/algaeconMar.htm >
It's starting to get too close to comfort to my zoanthid colony
on the same rock. Hope to hear from you soon. Best regards, Mark
Forsling
<A pleasure to assist! Mich> |

| Saltwater Question, grn alg. ID 4/8/07
Hey Wet Web Crew, <Kristin> I have a question regarding
something that has just "popped up" in our
tank. We have a 125 gallon saltwater tank, and this
green algae looking plant started growing at an enormous
rate. It has a round structure with "blebs"
that branch out, kind of reminds me of melted
wax. Currently there are two on the same rock, one is
about the size of an egg and the other the size of a golf
ball. I have looked all over, but have not found
anything that looks like this. Is this something that we
should take out or leave alone? <Likely
want to address... along with the evident BGA (the red mat.)... as
very likely a matter of excess nutrient... secondarily a lack of
competition, predation...> I have embedded the image so you do
not have to download, <Better to attach...> however if that
does not work, there is an attached file as
well. Thanks! Kristin <Do take a look on the Net re
the genera Derbesia and Bryopsis... and onto WWM re Marine Algae,
Control... can be controlled indirectly... as you will see.

| Algae ID 3/19/07 I have a
question about this photo (the one you saved). The
algae that he is asking about, the little green tuft on
the top left. I have this in my tank
also. I know it's not a terribly fast
grower, or at least mine isn't. It feels
like Chaetomorpha, almost looks like it too except that
is more straight than curly. It
doesn't grow terribly long either. Kind
of grows in a cushion. Can see some off
to the right in this picture from my tank (the color's
funky because it's under actinics). <Mmm, this
looks like Bryopsis to me... Cladophora is more "bushy",
straight, bigger, branched... http://images.google.com/images?q=cladophora&rls=com.microsoft:en-us:IE-Address&ie=UTF-8&oe=UTF-8&sourceid=ie7&rlz=1I7PCTA&um=1&sa=N&tab=wi>
When I was looking on WWM I found this that looks nearly
identical, though the picture is a little
fuzzy. In this photo it is ID'd
as Bryopsis. I found another picture... the
next one down where a similar looking algae is ID'd
as Cladophora. Are both of these
ID'd correctly? How do you differentiate
between the two? <URL please...> Bryopsis, a worldwide genus
of Greens that appear filamentous to spiky in
aquariums... light to dark green, generally
feather-like thalli. Some Hermit Crabs, Blennies,
Zebrasoma and Ctenochaetus Tangs may eat your type...
otherwise, scrubbing, competitive algae filtration are
recommended. http://www.wetwebmedia.com/greenalg.htm Algae ID-
These are showing up in patches on my liverock. I am
running the ecosystem and it has been up since June,
using Caulerpa as the main macro. Any clue
what it is? <It looks like Cladophora sp. macroalgae.
Looks nice, if it starts getting out of control,
just about any surgeonfish or urchin should readily chow
down on it. -Kevin> Thanks! Adam http://www.wetwebmedia.com/maralgid.htm <BobF> |

Chaetomorpha 12/15/06 I have two different types of
Chaetomorpha growing in my 29-gallon refugium: 1. The first
type is the typical "spaghetti algae" pictured on most
websites. It is very curly, and not too dense, much like a
Brillo pad for cleaning dishes. The individual strands are
quite thick, and it grows in a ball which sits low in the water (barely
any of it floats above the water, and if you take it out of water, it
collapses and lays flat). 2. The other type is very dense and the
strands are much finer & straighter. It grows in a
floating mat, maybe 2.5" thick. This type floats higher
in the water, and some of it grows straight up like grass. New growth
projects straight out of the mat in all directions, about 1/2"
long. The new growth on the top side of the mat is out of
the water, and looks like grass. If you take it one out of
water, it retains it's shape. The LFS where I got it
tells me this Chaeto grows just as well in freshwater as
saltwater. They have it growing in both types of water at
the store, and have switched it back and forth with good results. Is
the second type really Chaetomorpha? I can't find any
pictures on the web that look like it. <Your second type may be
Cladophora, can't say for sure without a pic. It may also be
Gracilaria, again, need a pic.> Is it okay to have both growing in
the same refugium, or will they compete with each other resulting in
reduced growth? Should I get rid of the second type?
<Chaeto does thrive on nitrogen and phosphorous and if the food
supply dwindles, so will the Chaeto. Having the two types together
should pose no problems. It is best to thin out on a regular basis. If
the outer edges begin turning brown, it is a sign that the needed
nutrients are absent or your lighting is insufficient for growth.>
Thank you, <You're welcome. James (Salty Dog)>

Re: Different Species of Chaetomorpha 12/18/06 I ran
Cladophora through Google Image. I have determined that my
second species of algae is, without a doubt, Cladophora
columbiana. Is this a beneficial species to have in my
refugium, along with Chaetomorpha? <Yes it is. Like
Chaeto, the Cladophora thrives on nitrogen and phosphorous. James
(Salty Dog)>
To-may-to or to-mott-o ... Chaetomorpha
pronunciation 6/10/06 Hey wet-guys and gals,
<Eric> Got a simple question for ya. How do you
correctly pronounce "Chaetomorpha?"
<"Key-toe-morph-ah"> Thanks,
Eric
<Bob Fenner>
| Algae ID 6/21/03 This is a
picture of what I believe to be some form of macro algae. Can you
tell me what kind it is and if it would be safe to use in
a refugium. Thanks <Cheers, Shawn... wish I could
help you with it, mate... but the pics sent are severely out of
focus. Rather a blue. Perhaps I could trouble you to take a portion
out of water and get a clear shot of it against a white
towel?> |
| Algae ID 6/21/03 I think these
pics will be better... Indeed... a Caulerpa species... prolifera
type. Can be a boon or a scourge depending on how well it is
managed. Too precarious and dangerous en masse for most aquarists
(noxious exudations) but rather handsome and good for nutrient
export if you are very diligent in keeping and harvesting it (thin
fronds... never cut them). Much is written in the WWM archives
about Caulerpa, refugiums, etc. Especially seek the FAQs. Bets
regards, Anthony> |

Little Green Bubble Things... Hi guys and dolls <Scott F.
your guy today!> We have a funky little situation. <As in
..."Play that Funky Music, White Boy..." or...?> I looked
at our 55 gallon reef today and noticed on a flat space on one of the
LR there are about 8 little olive greenish bubble looking things. I
have no idea what they are. We have a hammer coral, leather coral, a
white band cleaner shrimp, pulsing xenia, and star polyp . That's
it. Running around them are what look like copepods or some other
little tiny bug like creature. Any ideas what these "green
thingies" might be??? Thanks A lot. Have a wonderful day!!!
Christy <Well, Christy, I'd need a picture to be absolutely
sure...But I'll bet even money that what you're seeing is some
sort of "bubble algae", probably of the genus Valonia...They
come in a variety of tones, colors, and sizes, but are often a
transparent greenish color...Could be something else (like eggs from
the shrimp- but I doubt it.) entirely, of course- but that's my
guess. Still funky, though! Regards, Scott F.>
