Well I tested the tap water and got much the same results as the pool water so I got a new kit and tested the TA I had 170ppm and a pH of 7.6. I have added 4.5 cups of muriatic acid and now I am down to 160ppm TA and 7.2 pH.I have the fountain on and the slide water is also on. Everything is clear and clean so I am in the ballpark. Water temp is cold at 75, but considering the 56 degree well water that was used I can't complain.
