Please let me know if this topic is addressed elsewhere and I'll read how others have adjusted their pump. In the summer, our electric bill is outrageous. I just paid our June bill at $364. I asked my husband why he thinks our water still looks good and he said it's because he runs the pump 24 hours a day and never turns it off. We had trouble the first few years we lived here and someone told us that the longer he runs the pump, the better his water will look. Whenever he turns the pump off and then re-starts it, dirt and debris is forced into the pool. I've watched this with him and it looks awful. I found some information at this site about how to calculate the length of time to leave the pump running, but it doesn't make a lot of sense. Any ideas?
