I have seen a ton of post about saltwater damaging different flagstones and rocks. I am considering a salt system and will be using OK flagstone and moss rock. Can someone post some pics of the damage you have or have seen? There are several builders that request the customer to sign off on this for warranty purposes. I have not seen any pics, but would like to see how the saltwater affects the different sandstones. I would like to see what my pool might would look like several years down the road.
