We got a big rain (dilution) and afterward my SWG was measuring 2200. It was at 2700 before the rain. Thought that drop was a little drastic for a 3" rain, but I added a whole bag of salt anyway since it was a little low before the rain. Let everything run overnight and it's still registering at 2200, so I'm getting no chlorine generation.
SWGs are a black box to me, so I have no idea how to debug this. What should I do?
