So here's my situation.
27' round above ground, figuring roughly 18,000 gallons.
CYA has leaped to 212 this year. Feeding 1" Trichlor only and maintaining 7.0 ppm FC (give or take).
Used about 50 pounds of Trichlor in 5 1/2 months. Hard to believe there is that much CYA in a 50 pound bucket. I started new last year and only added 30 ppm of Stabilizer. At the end of that year we were at 130/140 ppm.
I'm at 212 this morning. (about 5 1/2 months open this year)
Other numbers just in case: FC 7.25; CC 7.25; ALK 125; CH 200; PH 7.4
My goal is to get down to 40 ppm, but slowly. I've read a lot of negative stories about draining an above ground pool. Using simple logic, since tap water has NO CYA, to get down to 40 ppm from 212 ppm I'd basically have to drain almost all the water.
I'm wondering if I wait until we are ready to shut down the heater for the year, and before winterizing, if I would pull about 1 foot out and replace, circulate a day, pull another foot out and replace, how many times would it take to get down to where I want to be? Anyone ever do it that way. I really don't want to take 75% of the water out at one time. The tarp method seems awkward..... uggh.
