Thanks again Watermom! Yes, pool service is once a week. So maybe I should do some testing on my own during the week. Its not like the pool came with instructions when I bought the house. I'm just going by what pool guy told me. After cleaning the water is so cloudy that you can't even see the bottom of the pool. I will extend the pump time. Do you run the pump longer during summer season? Sounds like I need a new pool guy!
