As a new pool owner, I'm trying to determine what would be the best speeds I could run my Max-Flo VS 2300 1.5 hp pump to turn over the water (18,000 gal) in a 24 hour period. As of now I have the pump set at first start-up to 3,000 rpms, for 4 hours, then it switches to 1,500 rpm's for 8 hours. 1,500 is too low for the heater I figured out, wonder if its OK for the auto chlorinator ?? I'm waiting on the completion of the water fall feature to see if 1,500 rpms is adequate as well. Trial and error right now in this early stage. Thx.
