Heres the deal and my question, my pool 13000 IG plaster, the Taylor book says ideal range for the follow PH 7.4-7.6 CH 150-400,TA 80-120 CYA 30-50 and the saturation Index should be <>.5 now my question if I use the data in the book, my numbers are out of wack,except for my TA, but if I use the Saturation Index I am within the limits. I am using BBB method, and slowly but surely I am bringing down my CYA and CH, I know the reasons why these numbers are so high, when I first had the pool built I was "dumb" I kept on adding calcium hypo pucks and trichlor pucks, thus my high readings, slowly but surely my numbers are dropping, I have done partial drain and refill to get them down to this, and will now wait for splash out and backwash to get them down to where the "book" says they should be. But, for the time being should I use the Saturation index to keep my pool "balanced" or use the book???? and because my CH and CYA especially my CH is so high, should I go ahead and do another partial drain and refill, or is my pool plaster safe.
Sorry for the long post, I might be making a "big" deal out of nothing, just want to make sure, and my water is sparkling clear
Thanks for you advice in advance
Pool Temp 78 degrees
