Is there a problem with salt corrosion of stone?

[Amir]

I guess there is no "perfect" way to keep the pool clean! I had considered automatic chlorine feeders (liquid bleach) but looking at my demand, i need to use 10 gallons per week. Then I had my mind set on SCG but I have both natural stone tile and coping (Torren) and saw some threads regarding corrosion of coping. Does anyone else have this problem with natural stone? Thanks
