One of the key methods Chemtura uses to maintain the myth of the superiority of its BioGuard line is misdirection and obfuscation, like calling baking soda (aka Balance Pak 100) "sodium hydrogen carbonate" instead of sodium bicarbonate.

The Mineral Springs SWCG falls under this marketing tactic of providing as little detailed tech info as possible. As a result, there's not much info available except to "premium" BioGuard dealers.

You'll probably need to talk to your dealer and hope they are educated and not just "premium".
