I am getting brown hair algea like no other in my tank right now. It is growing like crazy all over the glass and especially on the sand in the front of the tank. What can I do to prevent this or at least slow it down or kill it off.
Also, I have a lot of die-off from the live rock in my tank too. Could I actually take the rock out and scrub it softly with some kind of brush to get rid of some of this brown matter that is all over the rock? Should I siphon out all the brown matter that has fallen of the rock? My tank is exactly 1 month and two weeks old and is only 15 gallons. Is it too soon to do a water change? I have done no water changes yet. The guy at my LFS
told me to wait two months before I did anything with the tank.
