I take my pool water in and have it ready by a machine today.. Cost $5.00 if you don't buy chemicals, feel it is worth it since I don't have a test kit yet..
FC .39. Low so I put in recommended amount of bleach.
pH 7 added borax
Original filled pool from city water where my TA was extremely high. Took 4 gallons of muriatic acid to bring it down so that is why pH is out of wack. Hopefully SWG can keep clorine levels stable now.
