I am installing a Stenner 45HP10 pump. I have a variable speed pool pump that runs 9 hours a night and 6 of those hours is at 1,000 rpm (barely see water moving but it is) and 3 hours at 2750 to run the vacuum. So would it matter when the stenner pump is running as long as it's while the pool pump is running? Would it make a difference if it ran during lower speed times vs. higher speed? Pumping into the returns.
