A week ago I put a Hydor Koralia Water Circulation Pump in my 24 gallon tank. The day after I put it in my Coral Beauty died. She was in my tank for 6 months and was doing great before I put it in. My other fish that I had in the tank for two weeks did not do well untill I turned it off. Does anyone have one? What should I do?
