Our cold water formula is specifically suited for cold water pond applications with proven hardy strains and metabolic increasing carriers.

Our cold temp liquid microbe blend is the most concentrated pro-biotic supplement available in its class, at over 1.5 billion colony-forming units per ounce. One 32 oz. bottle treats up to 32,000 gallons.

APPLICATIONS RATES DIRECTIONS: 1 ounce, 6 teaspoons or 30 milliliters per 1000 gallons. Apply product near the pump or in front of the skimmer to allow proper dispersion through the filtration system. In new ponds or springtime start up apply daily for the first 2 weeks of filter operation. Continue treating at least 2-4 times per month thereafter as part of ongoing preventative maintenance.

Note: If extremely poor water quality exists like an ammonia test registering any levels or if pond is not properly filtered, treatment quantity may be increased threefold or 3oz, 18 teaspoons or 90m, for every 1000 gallons of pond water.

For optimal results ensure a pH pf 5.7-9.5; a water temperature of at least 41 F, and proper circulation via pump and fountain/waterfall.
