Algae Id?

[Be102]

this disappears until my lights are on then comes back slowly but surely. Any ideas?

 

[twilliard]

high possibility that is spirulina

 

[Be102]

Any idea how to treat it?

 

[twilliard]

If in fact it is spirulina then chemiclean is the only route but first it needs to be identified,
It does not look like there is enough to do my test (cyanobacteria) yet.

From pictures it doesn't look like cyno, but I'm not too sure. Wonder if my vibrant dosing will handle it.

Spirulina has the trait of seeming to go away and come back with the change of lighting.
I would watch it close or time to do a H2O2 cleaning.

I have never done a H202 cleaning; what is it?

Its when you use H2O2 applied to any area you want to rid of algaes and some bacteria. Let that H2O2 sit for about 4 minutes then place back into the tank. Presto!
No need to rinse rock.

Can I drop the water levels in my tank low enough to do such a thing? Will h202 (hydrogen peroxide?) do anything dangerous to my tank in general?

 

[twilliard]

H2O2 is harmless in this manner.
The best way to do it is to take the rock out that you want to treat.

It's possible to just kill the algae and not the live rock itself? Will it cause problems being out of the water?

 

[twilliard]

H2O2 does not kill the rock just the surface algaes. There is no issue with a rock being out of the water for 4 minutes.

Looks like my snail likes to munch on it!
