We are excited to contribute to protecting these beautiful lakes that contain one-fifth of the world’s surface freshwater, working to save the ecosystems that rely on the Great Lakes for years to come.

The Alliance for the Great Lakes is a nonpartisan nonprofit organization working across the region to protect our most precious resource: the fresh, clean and natural waters of the Great Lakes.

Spa Chemistry

Spa chemistry is quite different than pool chemistry.

Spas operate at much higher temperatures and hold a much smaller volume of water. The ratio of bathers to water is much higher in a spa, which means much more bather waste (sweat, lotion, hair etc.) is found in the spa water therefore spa water must be maintained quite differently than pools.

Tested and proven effective BioGuard products are known for delivering reliable results and making pool and spa care less complex. We carry an extensive line of spa solutions that match your unique needs.

Looking for a more natural way to sanitize your spa?

We also offer Spa Marvel. Spa Marvel Water Treatment & Conditioner is an environmentally-friendly, enzyme based spa water treatment product that reduces and eliminates the need for many of the chemicals used in traditional spa water treatments.

We encourage you to utilize our water testing service. This service is free of charge when you purchase our BioGuard and Spa Marvel products.
