So I posted about my 29g tank a few weeks ago with the water levels out of wack, ammonia at 8, Nitrite at 10 and Nitrate at 200 that was due to the 35lbs of live rock I added, things are fianlly starting to look good. Ammonia <0.25, Nitrite 4 and Nitrate 40, PH holding at 7.8. My question is, Does anything look wrong in the pic as far as how the powerheads are positioned and I guess that's algea on the corners growing. Should I try to clean it off or wait till i'm able to add some cleaners in there. I only turned the lights on to take the pic. Otherwise it's off till I add fish and verts.
