I am ussually pretty good with numbers, but this one has me bothered. I have a 18x36 humpback kidney IG pool with a 6' deep end. I have read a couple different estimates on capacity that range from 12,000 to 15,500. Now I figure this year I would try to nail it down. Before adding any salt it was 1720ppm, then I added 400lbs, it is now ay 4520, measure by salt test strips. I know there are not precicse, but it should get me closer than I am now.
Could any one help me and explain the fourmula that could estimate my pool capacity, thanks
