I am not sure what the issue is, but about a month ago I had my CH at 330. Tested yesterday and CH is around 400.
So not sure what the issue is here.
I had to fill the pool and tested my fill water, but since it is not mixing now sure how accurate it is.
CC=1-1.5 (cant remember off the top of my head)
Did not test for CYA
So can some tell me what may be going on?
