Ok I have finally got the CYA on the right track. So here are my numbers:
FC - 5.5
CC - 0
TC - 5.5
PH - 7.5
T/A - 130
CH - 480
CYA - 70
I know that the T/A and CH are too high. We tested our water going into the pool and it has alot of calcuim in it, so I have no idea how to adjust these numbers?
The pool water is sparkling clear but .... we still have some scale/calcuim comming in the pool and hot tub from the jets.
Oh we do have some raised algea it looks black but when you brush it is green. They are small about the size of a pea or smaller, and not many of them. I think brushing will get rid of it?
