I have a simple straight forward pool. 19,000 gallons with no frills and a Navigator with a dedicated line. I currently have a 1 HP pump on it and am thinking about going to a 2-speed pump. I don't think a VS pump would really do me any good. My question is will a 2-speed, 3/4 HP motor work ok? From what I have read online so far and looking at the pump curves, it looks like a 3/4 HP would work fine. I would run the pump on low for 15-18 hours and on high for 2-3 hours for the pool cleaner. Any thoughts would would be appreciated.
