Hey all.
21K pool, had CYA at 30 for a few weeks as I was SLAMing. Once finished, I added 5 lbs of dry stabilizer which said on the package that it was 99% or so CYA. Added it in a sock by a return jet and massaged the sock so it would dissolve quickly. Tested a couple days later expecting 60ppm but it was only 40! I don't think I have a leak but do have auto-fill but no auto-drain. I also have a solar blanket I keep on when not swimming, except an evening or two a week when I want the water to cool down. Water temp is between 85-92 F. Shouldn't 5 lbs in 21K gal have raised CYA more than 10ppm?
