Just wondering if there was a way to convert cal hypo weight to bleach gallonage (i.e. 1 lb of 53% cal hypo = X gallons of 6% bleach), or how to determine ppm gained per 1 lb of teh same cal hypo in a 22K gallon pool.
Just trying to figure out about how much cal hypo to use to bring my pool up to winter shock levels.
Thanks!

You could probably use BleachCalc to figure this out since I think it has different forms of chlorine in its menus/preferences.
At any rate, one pound of 65% Cal-Hypo adds 7.7 ppm FC to a 10,000 gallon pool and also increases CH by 5.5 ppm. This is equivalent to 1-1/4 gallons (20 cups) of 6% bleach (assumed to be 6.3% available chlorine by volume, not weight).
You can scale the numbers for your situation with different percentages of purity of Cal-Hypo and for the size of your pool.
Ah heck, I'll do it for you...in a 22,000 gallon pool one pound of 65% Cal-Hypo adds 3.5 ppm FC and increases CH by 2.5 ppm. You can scale this down for 53% Cal-Hypo, but should try and get 65% Cal-Hypo if you can, unless it's not as economical.
