Is there an absolute minimum amount of time that you should run your pump? My pump and cartridge filter are oversized for my pool. I estimate that my pump is pulling about 100 gallons per minute which means that my water completely circulates in just over 1.5 hours. I've read that the goal is to turn the water over at least once a day. I'm still figuring out how long my pump needs to run for the Aqua Rite to chlorinate my pool at the proper level, but ignoring that issue for now, is there a recommended minimum number of hours that you should run the pump so the water does not become stagnant?
