I woke up this morning and noticed that threw the night my tank got kinda cloudy. so i tested water, and everything was good at zero and my ph was at 7.0. So i did a water change anyway (6 gallon on a 20 gallon tank). Then i came home tonight and my tank is 20x's worse. The water tests fine. I turned the lights on to make sure my fish were still alive. And they seemed fine. The only thing is my water is CLOUDY! i can barely see my heater on the other side. HELP PLEASE!
