Hi all, hoping someone might be able to help answer a filter/pump question. I have an 18x52 round above ground pool with a Pentair Optiflo 1HP 60hz pump. We just opened the pool for summer (we're in San Diego) and I'm trying to figure out how long the pump/filter should be running each day. I've seen calculations online but the numbers aren't making sense. Any advice would be appreciated. Thanks in advance...
