OK. I will take out the trichlor pucks as I thought I read that it contained stabilizer. I will never bother with Calcium again.
Mine is 13,500 gal.
From Pool store:
My results Recommended
T/A - 70 100-150 (**printout said add 5lbs so I did**)
PH - 7.1 7.2 -7.8
CYA - 35 30 - 150
FC - .1 1 -3
TC - 1.1 1 -3
CC - 1.0 1 -3

The pool store said CYA was good but to add trichlor puck. I do not understand by recommended from above the CYA = 30 which is at low end but it is perfect. Is the recommended high end to sell more chemicals?

How much baking soda will raise TA by 10ppm?
How much Borax will raise PH by 10ppm?
If CYA is within range, do not use Trichlor?
