How old is the tank?

ridleywr24cb · 12/01/2012, 11:51 PM

7 months

Looks like some type of algae

hollister · 12/02/2012, 12:09 AM

I would agree. Maybe a low flow area..

Looks like cyano.

Is cyano just algae?

Cyano is bacterial-vegetable. Algae is vegetable.
Since it's green, I'd suggest a gfo reactor for a month or so. That will uptake any phosphate.
But run one experiment first: turn the lights out for 24 hours. If it goes away, it's a variation on cyano, and just protect the tank from all light (including its own) for 3 days, then start bringing up light in hourly increments per day---might have to do it 3 days every month for awhile.

Ok thank you

Wait.. how was this picture taken? It almost looks as if you are looking at the depth of the sand bed and not the top of it. Is this the case? If so, then that coloration is completely normal and I think is likely cyano that exists because of the high CO2 that exists with no flow in the depths of the sand bed.
