We have flagstone coping and pea gravel deck. The salt was constantly eroding the flagstone and seemed to always have sand in the pool. We recently converted ours to chlorine as the salt seemed to be eating everything up. The heater turned into a pile of rust and all the stainless light rings turned black. This is just my opinion but you may want to do more research and see if you really want a salt pool.
Good Luck

 

Not many pool companies will warranty any natural stone or flagstone on a saltwater pool.

 

You just have to seal it if you use flagstone. As far as salt vs chlorine, I'll take salt for sure. Way less maintenance.

 

Brick coping no problem.. river rock on perimeter-fine... my heater, pumps is 7 years, just normal chassis rust. Saltwater is 3000 ppm. Have aluminum patio deck furniture. Electroysis at feet has taken paint off. This may or may not be due to the salt effects. I would not use flagstone, or any cut stone unless you want to seal yearly. I am happy with my saltwater system, very low maintenance, and cost for chemicals is about $25 a month, which is 2 gallons of acid, and an occasional bag of salt.

 

Go cool deck type material for patio -easy on bare feet.

Stay away from stamped concrete - too slippery when wet.

 

Im looking at this as well, who are you going to use for the fiberglass pool?

 

Leisure Pools has the best warranty

 

I have built many salt pools with natural stone and no problems IF you properly seal it with Dry treat http://www.drytreat.com/Products/Protection/ENHANCE-PLUS on an annual basis
Fiberglas pools are ok at first,then they start looking like an old boat left out in the sun as the gel coat ages

 

Listen to surfdad he knows what he's talking about. He built my saltwater pool with natural flagstone coping and treated properly. We have had no issues at all and it looks great.
