Who has some good real world insight on saltwater and limestone coping? Traveling 3 days a week is having me second-guess not getting a SWG when I had the pool built. I'd like to switch over to salt. I have limestone coping. I've read all the horror stories. My thoughts are that limestone is soft and porous and will chip anyway. My 3 month old limestone already has a few small chips with no saltwater contact.
The pool builder basically says "Hell no. You just can't do it. You'll have a gravel pit in your backyard within months."
The TFP guys generally say it's overblown and that limestone will chip anyway eventually and that the salt content isn't as much as most think and the effects can be negated with a good seal.
As with most things, the truth is probably in the middle. I'm leaning towards sealing the limestone with a good penetrating sealer and going for it with a SWG. It's just the coping, not the whole deck. Who here has real experience with this? Barring a complete destruction of the stone, I think I'd rather deal with re-sealing and having a few chips than having to fuck with the pool chemistry on a daily basis. Hell, even re-doing the coping later on to something more durable would be a decent option to me.
