OWS Fall & Winter Bacteria Packs keeps your pond biologically active during the cold season when standard bacteria go dormant. Formulated with cold-adapted, high-concentration strains, this blend remains effective down to 38 °F, digesting leaves, sludge, and organic debris that continue accumulating under ice. By reducing buildup and maintaining oxygen levels, it protects aquatic life, prevents decay toxins, and minimizes algae risk for healthier spring water. The dry, easy-to-apply formula requires no mixing-just pour the pre-measured packets into the pond and let the bacteria go to work. Safe for fish, plants, pets, and wildlife, this pack ensures winter pond health and dramatically eases spring maintenance, giving you clear water with minimal effort. Ideal for backyard ponds, commercial lakes, and seasonal water features, OWS Fall & Winter Bacteria Packs delivers eco-friendly, consistent results for cold-weather pond management.
