I must confess that I didn't do any calculations re: the CL dump for 2 reasons; 1) I figured that I have so much "stuff" in there and 0 CL that it couldn't hurt especially if I was careful about not getting it on the liner and 2) although I'm a fairly smart woman I can't seem to deduct from Ben's table just how much ppm = on the CL test nor just how much a gallon of CL is = to in raising PPM. If you have any quick & dirty helpfuls on that I'd be eternally grateful. The pool place estimated my pool around 16,000 gal, give or take. I have a 52" with a 6'5" deep end with an 18" "ledge" surrounding that. (Doughboy never answered my e-mail or returned my calls)

I never dreamed that I'd need so much chem & math someday when I was slogging through the courses.

Thanks for the encouragement.
