    SWG for pool, but none for spa with waterfall

    I was about to pull the trigger and purchase an SWG for my 18K pool, but thought I'd ask this question first. I have a separate 4.5K spa about 25 feet away with a waterfall which I believe is made of flagstone, so I didn't want to put an SWG there due to problems with salt and soft stone.

    One thing I didn't consider is if a bather wanted to move from the pool directly to the spa... would that introduce much salt to the spa that could potentially hurt the flagstone? I suppose it depends upon how often that occurs, but just wanted some opinions.

    Not enough to be meaningful. Your spa already has salt in it if it is a chlorinated spa. Chlorine product, both liquid and stabilized add salt over time. It's not uncommon to see a non-swg pool with 1000+ ppm of salt in it.
