Algae
ID...Can Only Guess – 05/29/07
Dear Crew,
<<Hello Carmine>>
I have some bright pink and green algae growing in my tank. I've never
seen this kind before... It's kind of pretty. Is it bad or should I
ignore it? Sorry for the crappy picture.

Your pal,
Carmine
<<Well Carmine it’s impossible to say from the picture, but unless this
is Cyanobacteria I don’t think you need be concerned. Do have a read
here and among the links in blue:

Good or nuisance algae on rock 5/20/07
Howdy crew!
<Lynn>
I am curing some pieces of live rock that I found washed ashore while in
Florida (liked the encrusting coralline algae). After scrubbing clean a
couple species of green algae and one red have started growing. Not
certain of the species, one looks a bit like Batophora (first pict/red
arrow), though close-up images are hard to come-by on the web (and
didn't see anything in the WWM archives). The second shows the
filamentous green algae (red arrow) and a red one (blue arrow).
What are they, and what might each do if it got into my main tank?
Thanks in advance.
-Lynn
<Can't tell definitively from the images provided... but what is a
"weed", but a life form the perspective at hand has re utility, nuisance
potential... I would not panic here... These too shall likely pass (be
consumed, cycled/outcompeted... succession). Bob Fenner> |

Hi Bob,
<Jon>
No one ever got around to responding to me regarding this nuisance algae
problem I am having.
<Yes... am glad I saved your graphics>
I have reattached the photos, hopefully they are a better size. I am
trying to figure out what exactly this algae is and how I can rid of it
because it is taking over most of my substrate.
<Appears to be a "Blue Green", BGA otherwise known as>
Also, a lot of my coralline is fading on the rocks
<Likely either the BGA or whatever conditions are favoring/allowing the
BGA is at play here>
and I am getting a lot of white on the rock which look similar to
calcium or something of the sort. Am not sure how this all went haywire,
the tank has been good for a year now and all of my water chemistry
shows fine.
<Mmm, a bunch to say/state re the general changes, trends in aging
systems here... In a nutshell, it's easy for systems to become
"unbalanced" mostly in terms of alkalinity and alkaline earth/biomineral
ratios with time... A simple solution is often changing out, adding a
bit 20-25% of hard substrates (rock, sand...) and a one-time massive
water change, gravel-vacuuming (50%)... Please read here:

re>
Thanks for your insight
Jonathan
<And for the algae:

and as much of the linked files above as you can stomach, till you're
aware of your choices... Bob Fenner> |

Purple Yuk: A Most Accurate Description for
Cyanobacteria / Blue Green Algae / BGA – 05/08/07
<Hi Tina, Mich here.>
HELP!!!
<Will try!>
I have a 55 gal marine tank. It has been set up and running for almost
a year. About 3 weeks ago I started to see a bit of purple colored
substance in the sand, it has since spread throughout the tank and is
absolutely awful.
<Yep, been there, done that and would wholeheartedly agree!>
I do not know what it is but it is spreading like wildfire. It seems to
have air bubbles underneath the growth. It is slimy and
almost seems to have hair growing from it. Any ideas or suggestions?
<Yep, is Cyanobacteria, a blue green algae (BGA). Much more here and
the many related links in blue on ways to deal with this bad boy!
http://www.wetwebmedia.com/bluegralgae.htm >
I have attached a picture to give a better idea of what I am dealing
with.
<Oh, trust me, I know.>
Thanks in advance for your input.
<You are very welcome! Mich>

Re: What type of algae 4/24/07
Dear Wet Web,
Can a new tank that has cycled go through a stage where you are getting
Cyanobacteria but not an overwhelming amount. Because if this not the reason for
it.
<?>
Also am I doing the right thing by putting more flow into the aquarium with
powerheads and checking the Alkalinity to make sure it is not to
<too>
low. I have no nitrates or phosphates.
<None? Unusual>
Please let me know what you think.
I have it under control and also it seem to be going away very slowly after I
started doing 2 water changes a week instead of one. Jeff
<Much more to know, consider... You have read the articles, FAQs files on WWM re
algae control? BobF>
Little pics, I.D. and Valonia 4/18/07
How's it going?
<It goes well, thank you.>
I have attached five pictures of some different things in my aquarium
that I would like to have some more information on what exactly they are
and if they are good signs or not? I have circled the questionable areas
in the first four pictures. The first picture I circled some type of
algae or fungus that is spreading in other areas in the tank. Also
circled is some type of red algae.
<I see the pics, but they are very small and hard to resolve. The
circled areas don't look any different than the surrounding areas to me.
I would venture to say you may have some form of sponge started, but
can't see what I'm talking about.>
The second and third pictures are just some other areas where I wanted
to know what it was.
<Can't tell what I'm looking at, sorry.>
The fourth picture is some algae that looks like hair. What is this and
is it good?
<Can't see the hair, but I do see some "bubble algae" there. Not exactly
good, nor are they as troublesome as some other undesirables.>
In the fifth picture there is some bubble algae, this is the rock
bubbles started out and I have noticed some single bubbles in other
areas. How can I get rid of it if it gets out of trouble?
<They will probably not over-run the system, but you will be best served
in removing them by using a siphon. This method will keep the spore
translocation to a minimum when the bubbles burst. Their are also
creatures that will eat this, and competing forms of algae and life that
will control this and most other forms of deleterious algaes.>
Thanks for all your help,
Jared
<You're welcome. Try to make some JPG files, as they compress easily and
can be larger with more detail.
