Bleach Calc will only tell me how much bleach to add to raise my Cl.
I'd like to know how much Cal Hypo to add. I have a bunch of it, it's easier to store than bleach (I don't have the room for a whole summer's worth of bleach). I don't like running to the store all the time for bleach, so Cal Hypo is much more convenient. The stuff I used to use was HTH 68%, but I think a lot of folks bleached their liners with it, so they cut it down to 60% and it also dissolves easier.
I need a converter from 1 lb bags to gallons of bleach. Even better would be a converter that would not only do 60%, but any % available chlorine.
I'm still going to use a mixture of bleach and cal hypo, moving to more bleach if it becomes convenient to hit the stores or if I can clear out a closet. Can't store it in the shed, it gets too hot.
