Hello Everyone. I have been utilizing this site for a while and I have my first question. I have gone through the pool school section and have tried to find the answer in "search section". We have had water in the pool for about 1 month now. My wife and I were out of the country for the first two weeks and really don't know what chemicals were put into the pool to get it started. The pool builder sent his crew out and I'm not sure that he would get a accurate answer anyways. When I got home, I told them not to add anything else to the pool because I wanted to take it over. We finally had pool school last Wednesday and I started using my test. My FC was 18/ CC- 0/ CH- 250/ TA- 110/ CYA-60. I turned the Chlorinator down from 2.5 to 1 and took out all, but 1 puck. Saturday's test was about the same except CYA rose to 80. Today my levels are FC-16/CC-0/CH-250ppm/TA-110/ CYA-100. According tho the calculator I need to add 60%new water. When I talked with the pool builder he said that there isn't a way to drain water from the pool. He suggested that i add a hose and let the water drain into the overflow. Will that work? I could rent a pump and pump it out, if that would be better. I have truly appreciated this site over the past couple of months. Everything I know about pools has come from here. Any suggestions would be greatly appreciated.
P.S.- Overall, we are extremely happy with our pool and our pool builder. We would use him again if we were to build another pool.
