I mixed the water in the tank (maybe thats wrong but its always worked on the initial fill) as usual but did not have much circulation and I had a white film cake my side panels. This would not come clear. I then emptied the tank and put a razor to it. Two days ago I refilled with numerous powerheads running on it and the water was clear along with 99% of the glass with the exception of a couple spots I didnt hit. The water got more clear over the next day. Then, I woke up this morning to hazy glass again. Whats going on? I really feel sad about this. I am tempted to tear the tank down and not bother.
