I need a new pump for my 540 Gallon freshwater tank. The tank is filled with large predator fish such as South and Central American Cichlids. For filtration equipment I have a wet/dry sump, and 3 Ocean Clear canister filters. I probably don't need the sump, but it's a good place to put my heater, and I can filter out the large waste so my canisters don't get clogged as quickly. The 3 canisters T off after the sump so that the water is divided 3 ways before merging to go back to the tank. My question is: how big a pump do I need, and what company makes a good one? I had been using a big 1.5 horse Dynamo pool pump that I got used for $20, but it's starting to leak, and it was LOUD! It also probably cost me a fortune in electricity. The filtration is in the basement, so the water has to get pumped up about 8 feet to get back to the tank. Thanks for the advise!
