looking for advice. i have a pentair VSP and am looking for help determining run times for balancing proper cleaning and cost efficiency. my pool is 15500 gallons. currently it runs 2 hours at 3150 rpms for pool cleaner and skimming. then another 6 at 2000 rpms to just turn water over. thoughts?

As you have a SWCG, the first time requirement is to generate sufficient chlorine each day. After that, it is for skimming, and in your case, running the pump powered cleaner. After that, there is no requirement except for your aesthetic requirements. Turnover is a myth. Chemistry keeps your pool water safe and clean. The filter simply removes stuff that falls into the pool.

I would suggest you start with lowering your RPM to the minimum needed for the flow switch of your SWCG. Set that as the Pool Mode RPM. Then you can increase the RPM, as needed, for periods to run the cleaner and or improve skimming. The bulk of the time should be at the base RPM of Pool Mode. Do you have an automation system?

I have a two speed pump and have found that running 2 to 2.5 hours a day is sufficient for proper skimming and SWCG production. In the hottest part of the summer, I had to turn up my CG a little bit, but I have never had to run it at 100%.
