I plugged the numbers in when I was using the calculator a few minutes ago. Almost even. 5.4 vs 5.5 on my pool, assuming 73% cal-hypo, gallon to pound.
I also discovered something quite handy. For my 16000 gallon pool, one trichlor puck will raise CYA 2 ppm. I shoved 5 in the floater before we left town last week, they're pretty much gone now, and when I tested, it seemed like CYA jumped awful fast. But, in fact, it jumped exactly what it was supposed to. Back to jugs again until I replace some more water to lower CH.
