Just to answer your other questions....yes, you have the abbreviations right. Alk levels in a vinyl pool should be 80-120, but as long as it's under 180 or so you can live with it. I'd call 110 perfect, but you're fine at 130, too. Ph ranges are 7.2-7.8, so you're okay for now but watch that it doesn't rise too much over that. If it does, use muriatic acid to bring it back down.

Glad the problem cleared up for you!
