My in laws have a in ground saltwater pool with a spa that waterfalls into the pool, They live out of state now so Ive been taking care of the pool while the house is on the market. Up keep isnt too bad I empty the filters every other day (Takes a few seconds each) and once a week I have to add 16oz of acid, and a cap full of fos free , Once a month I add 1/2 bag of salt. It's a lot easier than a chlorine pool IMO . But after you add the chemicals the pool can't be used for 8hrs . The pool also has a Vacuum that cleans it soon as the pump turns on every day
