BigTallGuy: This is a Vinyl lined pool -- It has Resin top rails, bottom rail, and resin coated steel supports. Is that what you mean? Are you guys using them on pools with steel rails as well? It's hard for me to understand how such a low concentration of salt can be a problem but the warranty verbage sure does make me shy away from the steel rails.

BigDave: I got the specifics! As for the SWCG, I like the IC20 from ease of use and being plumbed right into the system. The hang on SWCG are less expensive, but I see myself hollerin at kids to leave it alone a lot too!
