I recently bought a 27' above the ground pool with the permanent salt system. I started reading about this after the fact and was freaked out to learn it doesn't sanitize the pool. I have a 2 and 3 year old swimming in my pool. I purchased my pool late in the season and I have been using chlorine in addition to the Permasalt products. The cooper has been high in the pool so i set the box on 2 (recommend 4)but the alkalinity has still been high. I know i need to make a change for next season cause financially it doesn't make sense. I am undecided whether to convert it back to chlorine pool or buy a saltwater generator. I have had a chlorine pool in the past and i understand how it works. But, I really want a saltwater pool however I don't know anything about saltwater hence the reason I ended up with the permanent salt system.
