Can someone please explain how the pump run time effects your pool chemicals specifically consumption and chlorine evaporation? I've seen a spot on ABC15 news here in Phoenix that Pool Kings recommends running your pump 1 hr. for every 10 degrees of outside temp. King said it helps circulate the chlorine and keeps it from evaporating. He went on to say you will save money on chemicals by running your pump as described above. Leslies Pool Supply has told me that same thing as far as 1 hr. per 10 degrees. I'm searching on the Forum and finding it is based on chlorine distribution, and keeping the pool debris free, and 4 hours is decent starting time. I'm currently running mine 6 hrs. and have a crystal clear pool, mainly because I've put into practice testing my pool every other day and keeping my chemicals balanced. On average I'm adding 12-16 ounces of 10% chlorine every other day and 24 ounces of 14.5% muriatic acid. Seems like a lot of chemicals but this is my first year doing this correctly and using liquid chlorine primarily, so I don't know what to expect. I also float about 2 tabs in my pool. I can't imagine how much chlorine I'd use without tabs. Thanks for help or reassurance!
