What is this algae? help

[jose227]

My parameters. Are all were they need to be. Very low nitrates very low phospahates. It's a 55 with a 10 gallon refugium with cheato. The system is been up since November 2013.

Looks like Cyanobacteria (red algae). I have the same problem. Try siphoning it out. How old is the tank?

 

[jose227]

3 months old. You think gfo will help

 

[Willba200]

What is gfo? Water changes, reduce light and up your flow

 

[Willba200]

But it will come back if you don't find what's causing it? Get your nitrate down

 

[jose227]

Nitrates are 0. I double checked with lfs. Gfo is media that goes in a reactor

 

[Willba200]

Algae consumes nitrate therefore it could be giving you a false reading. This happened to me. When I siphoned it out and picked off a load of green algae, I then tested my water and I was reading 20/40 ppm. How much is there?

 

[Willba200]

My tank is only three months too, it's a hard hobby but I'm trying to stick with it. What do you have in there out of interest?
