I hope this is not bad?

I have a turquoise or a greenish blue growing on my rocks is this a bad thing?

flamingo · 01-12-2007, 09:30 PM

Possibly cyanobacteria. And no, it's not the greatest thing to have.

fishfingers · 01-13-2007, 12:57 AM

Can you take a picture? If not try and give us the best description you can or even draw a picture of it.

Reefneck · 01-13-2007, 05:29 AM

Cyanobacteria is "Cyan" in color. Not turquoise or greenish blue. Could be coraline. Depends on how long the tank has been running.

A picture would be the best thing to help ID this, but I have yet to see cyanobacteria other than in BIO class so If someone could it would be nice to see a pic posted of what a tank looks like with cyanobacteria

there are a lot of types of slime algaes that would definately fit the color description. Is it encrusted or slimy?

Greenish blue what? COuld be anything from a polyp to bga. Could you add a little more description?

cyanobacteria actual means blue-green algae. I would not have guessed it. I've been researching it lately after post was writen. It appears that the maroon algae I thought was new coralline is cyanobacteria. Ouch. Anyways I did discover that with a high level of disoved organic carbons this bacteria thrives. One of the main reasons this is bad is that it will choke the life out of other organisms in your tank. Which in turn creates more food for the cyanobacteria to grow.
So, how to get rid of it? I have seen 3 different products on the market to take care of it. Anyone ever use these and which is the best?
My main problems were poor water flow in my tank and my skimmer not working as good as it should. Without the organic carbons making it the skimmer this bacteria is bound to be a problem.

I've used freshwater maroxy half dose every other day...

GoodMike · 02-06-2007, 11:33 AM

the problem with just treating with a chemical is that it gets rid of the cyano, but doesnt get rid of the problem causing it, and you will have it return. you need to find why you are getting cyano, i have found alot of times it is due to too much feeding and not enough cleaning, or not enough water flow.

Usually people (that can do this) do a short blackout period with some type of bacterial med. Since it's a photosynthetic algae it can't use light for food, and since it's a bacteria.. well you know

.

Sigh, we're studying this in biology

If its a reeftank though i would just try to increase flow, it works like a charm.
