So it appears my PB put way too much CYA in my new pool. Multiple tests are coming back at 110. I have been keeping my FC north of 5ppm but would prefer not to have to leave it up there. I need some confirmation on my thought process on lowering my CYA.
Its currently at 110 and I want it to be at 75 as recommended by my SWCG. 75/110=.68, 1-.68 leaves .32 or 32% of fresh water required to lower my CYA down to 75. Is my thinking even remotely correct?
