Maybe I need to align my calculator...........
Borax is effectively 11% borates; on a 10,000 gallon pool, you need 45 lbs of borax or about 545 ppm borax to achieve 60 ppm borates.

Paul, I don't mind correction (well, sometimes I do, but I put up with it) when IT IS CORRECT! But, I get pretty impatient with folks who come here and start sharing their wisdom -- ESPECIALLY WHEN THEY START POSTING MULTIPLE TIMES IN DAY -- without first checking to see if their wisdom is (a) correct, (b) relevant, & (c) helpful.

You've been warned: ask HERE, before you post, elsewhere!
