I have been a pool owner for all of 10 days now and I tend to run the pump 4-8 hrs. a day. My water is testing excellently and it's pristine sparkly, but I think I'm running the pump WAY too long. I want to cut down, but don't know what is optimal. A little info on the pool & filter combo is in my signature. I'm running the pool around 16K gallons and the pump is rated for a 38K gallon turnover in 4 hours, so my pool is being turned over in just under 2 hours. If the rule of thumb 1 turn-over or is there such a rule? Thanks in advance for the help!
