Last night I covered the pool with the solar cover and some water got on the cover. Today I note that there is some salt stain where the water was. Not a lot, but it's there. I also note on the edges of the solar cover there is a bit of salt too. I've had the SWG running since May and haven't had any problems. Salt is at 3200 ppm. Also, when I cleaned the pool this past weekend with the auto cleaner and was cleaning the bag, I noticed some bits of salt in there. I've never noticed this before. I thought all the salt would be dissolved, but maybe not?
Is this normal?
