I recently upgraded my son's 5 gallon to a 10 gallon tank due to very green and cloudy water that would not go away with water changes. I knew that by going bigger it might be more stable and I was worried about his fishies. We went ahead and moved the fish in (we lost a few in the cycling process). I have noticed the water getting cloudy again. I have checked the water 0 ammonia 0 nitrites and 10 nitrates. Am I still cycling, and are these good? Should reqular water changes help the cloudiness. Also he keeps his hood light on all the time (at night as a night light) and during the day. Would this be causing the cloudy water? Any help please!!!
