my water started getting cloudy the other day after i added a few pounds of LR . is the lr the cause or am i getting an algae bloom. i did a 10% water change. and then i turned the lights off for a couple of days and it started getting better, but when i turned the lights back on it clouded up again. not supper cloudy just enough to annoy me. the only fish in the tank is a pink spotted shrimp goby. just dont wanna hurt the little guy. any ideas on what is causing the cloudiness...algae bloom???
