    borax

    If my pool holds 17,000 gallons (its 28' round 4' deep) what should my ph level be? I'm trying to determine how much borax I need to add. My ph is 7.2 now chlorine is on the high side.

Should I have kept going? I'll try again when I get home later...

    Liner Cut Too Small

    Thank you for your responses. Installer wants to stretch it. The pool is already filled about half way and there is a cut out for main drain and skimmer. Can it be stretched and will that affect the cut around main drain?
