22,000 gal IG plaster. I'm using the PS230 testing kit I got a few years back. I've replace the chemicals a couple of times incase your wondering. The CH has always been good. This is the first time I got a low reading (150). It say's in the PS230 booklet that this may eat away at the plaster. Don't want that!
I've gotten great guidance here before and was hoping that a good solution could be found. I wanted to gather some opinions before going off to the pool store and getting the pitch. The guys pretty good but still would rather me buy a new plaster job than add a box of "fix it" from the grocery store.
