So I got my orientation today from the pool tech. I asked why the installers put SO much salt in (SWG is reading 4700PPM, but still producing chlorine.) He didn't have an answer, figures they messed up.
Anyway, I was talking to him about chemicals and I said the chlorine is getting used up VERY quickly, especially since there's no CYA in the pool yet. He said good - let the SWG keep generating chlorine since it's getting used up so fast to get the salt level back down. I didn't argue, but that didn't sound right to me at all. I just read in the pool school that as the chrlorine gets used up, it turns back into salt. Interesting. So he was wrong (Which is also interesting.) Am I reading this correctly?
So my question is - why over the course of a summer do people have to sometimes add salt? Is it due to water simply being splashed out and such? I read somewhere else that salt does not dissipate as water evaporates. If so, then it's simply for people splashing about. Same question for when opening up in the spring. We have an auto cover and as such, we'll have to keep our water level where it normally is to support weight for snow and such in the winter for the cover. So would I need to add salt in the spring?
