Cold Weather Beneficial Bacteria

Pond Biologics® Cold Weather Beneficial Bacteria contains a highly concentrated blend of psychrophilic (cold loving) microorganisms that are capable of reproduction and function in cold temperatures, essential vitamins, and catalyzing enzymes. They infuse bacterial cells with the vitamins, minerals, and amino acids essential to healthy and robust cell development.

This microbial blend is formulated for water temperatures under 50°F.
