Looks like my 25K gal pool has only 110 CH - probably because the water we're topping it up with is more like 80 CH. Pool Calculator says to add 32# CaCl to bring it up to 250 CH. I plan to add about 8# at a crack and test to make sure I've got it right.
Supposedly AceHardware.com sells a 50# sack of Qik Joe flakes for $22.99 with free shipping to a local store. Have any of you guys successfully used this stuff? Ordered from Ace?
Thanks for your help!
PS just for reference, other values are FC = TC = 4.5, PH = 7.6, TA = 90, CYA = 50.
