Ok so we have had our AGP for about 6 weeks and we are completely new at it. The chlorine is forever dissipating (even if I have two 3" tablets consistently floating in the pool) and I end up shocking it once per week. Which is fine, but I have yet to get it to stay at a level playing field. Its either too much(after shocking) or not enough. The ph seems fine consistently. My calcium hardness was 240 so I added the 20lbs calcium in two separate increments, so far. However I tested today after shocking it last night and the hardiness is off the charts. It is way worse then it was a week ago when I added another 10lbs. UGH!! I am so confused on how to fix all these issues. Every website or pool place I call gives me a different answer. I don't know where to begin! Anyone please help????
