Do Salt Generators damage limestone/masonary

[chem geek]

I have a DE filter and backwash as needed (via pressure readings).

Thanks. So your salt levels in your pool are probably in check and well below 1000 ppm. That would make the quality of the stone the dominant factor in your corrosion. So "craiga's" pool builder shouldn't be using the fact that a pool has salt or an SWG as an excuse for what may be poor quality stone.

Of course, the problem is that there may be times when higher salinity is indeed a problem especially with certain types of stone and yet this whole issue gets muddled as fingers point to whom to blame. And there are other times when not using CYA, with the result being very high disinfecting/oxidizing chlorine levels, may be the primary source of corrosion (a possibility in this thread).
