we have bought a pool for the first time at our home. It is 22,000 gallons according to the pool store the previous owner went to. It is in ground with a sand filter and inline chlorine feeder. I have the tfpro kit and have been trying to slam for a few days but the water is still really cloudy. I took in a sample to get tested today and my numbers for fc were double the pool company computer test output. I tested at 8 and they tested at 4.2. So I am not sure what to do next to help get the pool not cloudy and finally be able to use it. My cya is just under 30, my alkalinity is 100, ph is 7.2, calcium is 175.
