I have been having heat problems with my 125-gal tank. I know that the source of the heat is a mak-4 pump that pumps water from my sump to the tank. The tank water is always about 10 degrees warmer than the air. Even in winter here in Minnesota the tank will be about 80 degrees. I asked a local fish dealer about the problem and he told me that I'm just going to have to put ice in the tank constantly. I have asked a similar question before, but I didn't get the help I needed. I know ways of cooling the tank down like fans, ice, and chillers. I have also used a quiet one pump on this tank and I had the same problem. WHAT I NEED TO KNOW IS WHAT PUMP CAN PUMP AT A GOOD RATE AND STAY COOL.
