New house to me with an in ground vinyl liner pool, 40,000 gallons. Opened it two weeks ago and water was clean and clear, I have a Hayward automatic chlorine and use 3" pucks. Took water to my pool supply store three times now results have not changed . Fcl .6 tcl .6 ph 6.4 alk 40 ch 150 was the figures yesterday. This is post 30 pounds alk plus, 15 pounds ph plus. I just added 2 gallons liquid chlorine and 5 boxes of borax. My current self test using the pro 7 kit is fcl 6.60 tcl 8.42 ph 6.5 alk 63 ch 56 cya 116 so far this clear water has cost me 200 plus and I can't seem to get any numbers to change to what's needed. Please help have a de filter that I back washed again today and recharged.
