CYA from pucks

[rjb1211]

I know that I saw the answer to this here before but I can't find it.

What is the math of how much CYA is added per 3" trichlor puck or per pound?

It depends on your pool volume. The ratio is such that every 10ppm FC added by trichlor raises your CYA by 6ppm. Use PoolMath or get the App to help you with your specific calculations.

That is what I needed. Thank you.
