18x34x52 above ground Doughboy pool 15 years old, Hayward sand filter, 1.5hp hayward. Ok so i love my Nature 2 catridge for the fact u use hardly any chemicals and your skin feels nice but..... 0.5ppm goes away fast once the heat of july and august arrives and heavier bather loads. I was also using chlor tabs and had put a couple pounds stabilizer in beginning and now my CYA is 100. I cant get chlorine to stay. So now i took out the tablets and am using liquid chlor to raise chlorine daily. Next season im not buying a cartridge im going full out BBB. The only time i may use diclor tabs is if i go away and cannot manually add chorine.
