I have a couple of pool pumps left over.(1hp) I was wondering if I ran lots of water through it could I eventually use it to run a tank and if so how would I go about it? Thinking about a 900 gallon pond
Pool pumps are high in amps which will cost you $$$$ to run 24/7. For a 900g pond you can get by with a 1/16HP or 1/15HP (1.3amp) pump. 1 HP (10amp +) is overkill.
