Took me a minute to find out that "Mineral Springs" is just BioGuard's hokey attempt to have a 'me-too' salt water chlorine generator. Their program is just a standard SWCG program with borax.
Anyhow, BioGuard doesn't make those units, and I don't know who does. I think you might want to call them -- BioGuard that is -- for all their hokey marketing, they have had some pretty good customer support folks in the past, and they are going to have way more access to info about that unit than I do.
Over the past few years, as Chemtura (and all its predecessors) has had a harder and harder time positioning their flag ship product line (BioGuard) as the "Rolls-Royce" products of the pool industry, they've made it harder and harder for anyone to get accurate info about their products. You can't even get an MSDS on for their chemicals on the Internet any more.
So . . . accurate info is going be available from them, if at all. Their phone number is BioGuard Customer Care - 1.800.932.5943 . You should feel very free to call them, given the premium they charge for their products.
Good luck!
