BioGuard Mineral Springs Beginnings is the first step in the Bioguard Mineral Springs System. Beginnings creates a total mineral bathing environment and is a natural way to automatically sanitize pool water. The Mineral Springs System utilizes easy-to-apply minerals and a chlorine generator to produce a chlorine sanitizer. It takes only five minutes a week to maintain - in fact, once you've begun the system, you only have to add the Renewal product once a week.
