We just had our new pool installed 2 weeks ago and I found this site just in time. I used the tablets that came with our pool while I was gone on vacation this past week and I ran out of them. So I purchased some liquid chlorine and decided to go the BBB route. My test numbers are CYA<30, FC 3.5, CC 0, TA 100, CH 110,PH 7.6 and the water is crystal clear. I am going to check the FC in the morning to see if I have any overnight loss. I guess my first step would be to get the CYA up a little bit and then go from there. Any how this is a great website and I have learned a lot in the past few days of reading.
