You'll want to do a lot of reading on this site: Pool School, Pool Math.4 gallons of acid, two bottles of Jacks Magic magenta stuff, chlorine tabs in skimmers.
Tested water this AM (with TF100 kit). FC2, ph 6.8, TA 110,CH 300.
Any thoughts on numbers? Should I wait for higher ph to swim? Will it come down on its own or should I add borax?
