About four weeks ago, I emptied everything out of my 120 gallon tank to paint the back. After that, I filled up the tank and began cycling. I ran my XP3with the old media and The first week it was perfectly clear. After two weeks, I performed a small water change and added my first fish. A couple days later, my tank broke out into a MASSIVE bacterial bloom. It was milk white and I couldn't see the back at all. A thick sort of foam had formed at the surface, and there was a noticable smell. Upon looking at a certain angle, I could see millions of little white dots swirling around. I figured a bacteria bloom was only normal a couple weeks into cycling. About a week later, the bloom cleared and my tank was crystal clear again. After a couple of days, my tank started getting cloudy again, but not as much as the first time. I did a water change and it cleared up within hours. Now, a day later, my tank is fairly cloudy again. This morning it was clear. There is a faint white coating on the sides of the tank and little white specs on the glass. Please, can someone tell me if I am doing anything wrong, or is this normal. I have been cycling for about 4 weeks, adding doses of beneficial bacteria every couple of days. I just want my tank to clear up, and stay clean.
