I just finished moving the family to AZ from CA and have a new to me house and pool. The water is a mess (TA and CYA are off the charts) and will be draining it this week when we have a couple of cooler days. I used 12% liquid chlorine in California and had a shop that carried returnable 4 packs 2 minutes away. I'm still searching to see what my options are here, but wonder if the pool would be a good candidate for salt? The coping is brick and the deck is slate tiles. There is a waterfall and I'm not sure what the stone is. The slate has some minor flaking and my concern is whether the salt will damage it more rapidly. Thanks for any advice.
