From what I'read, he already has plants, which would explain the lights being on for 10 hours a day. What kinds of plants do you have? I would try a black out. I had really bad green water, so I turned the lights off for 4 days, and when I turned them back on, my water was crystal clear. and yes, I did have plants, but they were anubias, so they were okay with the lack of light.

what kind of fish do you have? is the water green cloudy, white cloudy, or brown cloudy? White cloudy would be a bacterial bloom, which is from the cycle...it should go away within a few days. Green cloudy would be an algae bloom, and I recomend 15-20% water changes daily, along with a black out until you water is clear. I'm not sure what brown cloudy would be from. About a week ago, I did a normal water change on my 10 gallon, and switched lights of of another one of my tanks(instead of 2 20 inch flourescent fixtures, I had a 28 watt t-5 and a 15 watt flourescent) and 2 days later, when I came home from school, my water was brown...so brown I couldn't see anything....I immediatly did a 30% water change, and took the t-5 off, and put my second 15 watt flourescent fixture back on, and the next morning, my water was clear again.

hope that helps.
