Trying to get my pool closed and cannot get the FC to stay at SLAM level... Brought it to 13 FC yesterday.. 24 hours later, just tested and its at 6 FC..
CYA around 50
CC under .5
Water is crystal clear.. I had an issue with FC not being able to hold and ended up having a phosphates issue.. They were over 1,000 and had algae on the bottom of the pool and cloudy water when that happened (about a month ago).. Treated and phospates were down to zero (haven't tested again)..
What should I do here?? I really wanted to get this closed.. What is eating all my FC!?
