This is probably going to be a dumb newbie question. . .
I have a Hayward SWG and understand that the SWG% is basically for runtime of the SWG.
But - as salt levels go down over time in the pool, do I need to run the SWG longer (Bump up the %) to compensate for that? Basically, is the SWG making less chlorine, at the same SWG% level, as the salt in our water goes down over time? I have to ASSUME the answer is less, as less salt is passing through the unit. I'm running higher this year on the SWG%, and that's my assumption as to why.
Last year was the first year for the pool and the builder dropped in (As per the SWG) about 4200PPM. JUST below the threshold for the Hayward to stop making salt I believe. After a season and half, we're now down to 3800PPM.
