Here were the numbers today (sorry don't have the fancy test kit):
Chlorine - 5
PH - 7.2
Alkalinity - 170
Calcium - 200 (I know this doesnt much matter for vinyl)
CYA - 0 (can't understand this because I used trichlor tabs all last summer)
No phosphates
I just added 1.42 gallons of 6% Clorox. I also tried the Vitamin C tabs and that did nothing against the liner.
