I have a container of trichlor pucks left and need to raise my CYA. How can you calculate how many pucks to use in my automatic chlorinator to raise the CYA level. They are 85% chlorine. Mt Cya is at 35 and I want to raise it closer to 45 or 50. I am going through a lot of bleach this summer and didn't have that problem last summer when my CYA was at the higher level

Use the Pool Calculator, link in my sig. After adding pool gallons at top, Scroll down to the "Effects of Adding Chemicals" section.
