I finally purchased the taylor Chlorine FAS-DPD and tested my pool and typed in the results in the pool calculator. Here are my results.
also used the Lamatte borate test kit and the result is 50 ppm.
I have no idea if its living in Phoenix AZ with this heat, but I can't keep my FC at a stable state losing 2ppm per day. I know my CYA is off but getting mixed info on emptying half my pool or getting a CYA reducer. Please help. It's getting expensive keeping the FC at normal levels.
P.S. lower the PH tonight to 7.6
