My pool store (the one who does all the Warranty work for my Pool Buider) ushes their Mineral Springs SWG system. I refuse to listen to them for the same reasons. They won't tell me what is in it besides salt and why I should have to apply their "Renewal" product every week instead of just Muriatic Acid as needed. It has to have ph down in it and additional salt. It also has to have CYA in it per their literature (http://www.bioguard.com/mineralsprings.shtml) and we all know adding CYA regularly does. However, what else it has is like the "magic" stuff in your Ocean Breeze system.

The guy who openned my pool from the pool store almost had heart failure when I told him I used solar salt from Lowes as my salt source.
