I have a 30gal freshwater tank. At the beggining of this year, I had a problem with the water being cloudy which soon turned into a non transparent green. I used 2 treatments.. one to clear the cloudiness and one for the "bacteria" supposedly causing this. After 2 weeks and 6 filters, it was crystal. A week ago, i cleaned the tank and changed water as needed.. now its back! This time, its foaming on top of the water and has killed off 9 fish in 3 days. Any help or advice please!?
