I just got a New IntelliFlo VS+ pump. I have read several of the posts and found the spreadsheet online but I am still a little confused on how long I should run my pump. I have a 33000 (20x40) pool and 2 in piping. From what I read it seems like I would need to run it for 5 hours on high speed to get 1 water turn over. Is that correct? Or should I do a combination of high speed and low speed?
Besides the spreadsheet how can I tell how many GPM I am pumping? How long should I run?
