Yep, you're correct, I'm using 121oz jugs. And apparently I just have a faulty memory; I just realized I'd done the math last weekend to figure out I'd need approx 2 jugs to get to about 10 ppm of chlorine, and then promptly forgot! Which explains why the pool has turned greener again in the past 2 days, I've only been adding 1/2 the chlorine I need!

So back to WallyWorld for me tonight since I used the last of my bleach last night. Glad they're open 24 hours...

Question- where do I need to keep my pH in order to break up and degas the excess kH? The pH has been climbing pretty quickly.

(And sorry- I truly wasn't expecting a reply in the middle of the night, just wasn't sure I'd put this thread in the right forum to start off with. I guess I didn't since you moved it, thanks. )
