PH > 8.2 "did it at night with house light so I can be wrong"
CYA < 20
So my PH, CH and TA are high and CYA is low. I need to fix this. what is the best way to do it? I took a fast look at the pool calculator and looks like PH and TA are related/effect each other so I still don't get it. CH value seem high, double the recommendation. and my CYA is very low.
What is the best way to fix the pool? I have bought last year a lot of Chlorine pucks but never used them as I was told they will increase the CYA levels which were good last summer, now that my levels are low I am thinking of using them and keep testing for CYA until maybe it reach 35-40 then stop using them. I live in Plano, TX and the pool under the sun from 10:00 to 11:00am until the sun goes down. "gets lots of sun"
