Brown stuff on rock

astronaut69 · 10/29/2013, 06:32 PM

What is this powdery brown stuff? It gets on the glass, the sand, and rock. My tank is 10 months old. I did a series of large partial water changes; and do 20 percent every 2 weeks. My phos and nitrates are zero. I feed a small sheet of seaweed per day and frozen 3 times/week. I have cut back on lighting. Can't seem to shake this stuff.

It's tuff to see from the picture, but I would say detirus.
