Having an automatic pool cover on the pool in my new house replaced, it was paid for by the seller as part of closing since the old one doesn't work any longer. In any case the installers came out today to install the cover, due to ordering the improper cover they will be back but after my wife mentioned I was installing a SWG they said do not because the salt will corrode the guide rails and mechanical components of the cover. I know salt can be corrosive but I didn't think I would have a big issue at 3000-3200ppm, anyone have insight? I really enjoy the low maintenance of the SWG and don't want to give it up at this house unless I work a good alternative.
What alternatives make sense, does the fact that this pool is gunite have any bearing on the use of an SWG. vs. liquid chlorine (I know in the end the same thing comes up, just gradually with the SWG), vs. other sanitizer options?
