View Full Version : Black hair algae?

I beleive the live sand in the bottom of my tank has black hair algae. It is starting to turn pure black (top layer) and has hair. My levels are fine, I am using the stock light that came with the 75 gallon tank but only leave it on 8 hours a day.

Current stocklist is 4 clownfish, and a bunch of snails and crabs. The tank is filled with rodi water.

How can I get rid of the black algae? It looks awful and I'm about to give up on it. Tank has been running since November.

Really need a photo, but all algae problems come down to one thing: too much nitrate and phosphate.
