I finally got the new regents and did my test (TF100 kit];
FC 2.5
cc .5
CH 475
TA 70
PH 8.2
CYA to the top of the bottle 10??
I add chlorine at night, usually enough to bring FC up to 7. I have had past problems with PH but it runs 7.5 to 8.2 Historically CH is in the 350-375 range so its high. TA looks good.
Pool is clear...
How do I lower the CH and raise the CYA.
