I am leaving for a 7 day vacation (Key West if you must know! ) and I would like to be able to keep the pool as low maintenance as possible. I keep my pool b/w 3-8ppm with my CYA around 35ppm and borates. Should I buy a few tabs and put in the skimmer? I know they are stabilized but how much will this raise my CYA? How long do they last and what will it maintain my chlorine at? Or, is there an unstabilized slow release chlorine?
