Description
The Microbe-Lift Autumn/Winter Prep (56263) is a 1-gallon professional-grade pond winterizing treatment — a two-part system of liquid cold-weather bacteria and dry water-soluble packets packed with cellulase enzymes and cellulase-producing bacteria. Together, these components accelerate the breakdown of leaves, organic sediment, and sludge throughout fall and winter, protecting fish during dormancy and dramatically reducing the algae bloom and sludge loading you’d otherwise face at spring startup.
The psychrophilic (cold-loving) bacterial strains maintain sustained biological activity in water temperatures under 40°F (4°C) — effective even under ice and snow in darker conditions. If the product or treated pond freezes, the bacteria remain fully effective after thawing. Begin treatment in fall as water temperatures fall below 55°F, before cold-weather bacteria in standard pond treatments go dormant.
- Liquid portion: 32 oz per 1,000 gallons of pond water (initial fall application)
- Dry enzyme packets: One packet every two weeks, continuing until water temperature consistently remains below 40°F (4°C)
Verify gallon packet count on your kit label — the 32oz quart includes 4 × 2oz packets; the 1-gallon kit contains proportionally more.
Why Proper Pond Winterizing Matters
Most spring pond problems — algae blooms, ammonia spikes, excessive sludge, fish stress — trace directly to poor fall and winter preparation. As leaves and organic debris accumulate on the pond floor through autumn, they decompose anaerobically under ice, producing hydrogen sulfide gas and depleting dissolved oxygen. Fish in dormancy are highly sensitive to these conditions even though their metabolic rate is reduced.

Frequently Asked Questions
How is Autumn/Winter Prep different from regular pond bacteria?
Microbe-Lift Autumn/Winter Prep uses psychrophilic bacteria — cold-loving microorganisms that remain active in water temperatures as low as 40°F (4°C) and below. Standard summer pond bacteria (like Microbe-Lift PL) are mesophilic strains that go dormant when water temperatures drop below approximately 50°F. If you apply summer bacteria in fall expecting winter protection, you’re getting no biological activity once the pond cools down. Autumn/Winter Prep keeps working through the cold months and is effective even under ice and snow.
What is in the 2-part 1-Gallon Winterizing Kit?
The kit is a two-component system:
- Liquid bacteria: Cold-weather bacteria and liquid bacteria that provide initial breakdown of organic by-products
- Dry water-soluble packets: A blend of cellulase enzymes, cellulase-producing bacteria, and cold-weather bacteria specifically formulated to break down the cellulose structure of leaves, pine needles, and plant debris
The liquid handles the initial bacterial colonization of the pond bottom; the enzyme packets provide the specialized cellulase chemistry needed to break down leaf and plant material that standard bacteria cannot efficiently process. Note: The dry packets in this kit are the same as the Microbe-Lift Spring/Summer packets — if you run out mid-winter, the Spring/Summer packets can be substituted.
How does this product help with Spring Start-up?
By maintaining biological activity through winter, Autumn/Winter Prep prevents the accumulation of nutrients, ammonia precursors, and excess organic sludge that fuel spring algae blooms and fish stress. In an untreated pond, fall and winter leaf decomposition creates an organic nutrient load that, when spring temperatures activate bacterial and algal growth, produces intense algae blooms, ammonia spikes, and sludge foam. A pond treated with Autumn/Winter Prep enters spring with a dramatically lower organic load — clearing faster, experiencing fewer ammonia spikes, and requiring significantly less spring intervention.
What is the coverage area for the 1-Gallon kit?
The liquid dosing rate is 32 oz of liquid per 1,000 gallons of pond water. At 128 oz per gallon, a single gallon bottle provides enough liquid for approximately 4,000 gallons per application. For seasonal coverage (multiple applications across fall and winter), contact Microbe-Lift directly for the confirmed seasonal treatment area for the 1-gallon kit at your pond size and leaf load. The packet dosing is one packet every two weeks until water temperature consistently stays below 40°F.
Is this treatment safe for koi and goldfish during dormancy?
Yes — fully safe, and actively beneficial for fish. All bacterial strains and enzymes are naturally occurring, non-toxic compounds that will not harm koi, goldfish, aquatic plants, or wildlife. In addition to being safe, Autumn/Winter Prep actively helps fish by reducing the dissolved oxygen demand from decomposing organic matter (which would otherwise compete with fish for oxygen under ice) and by maintaining water quality that supports the immune function of fish during the physiologically stressful winter dormancy period.
Should I continue to run my filter with this product?
If you keep the pump and filter running through winter, the psychrophilic bacteria will colonize your filter media and provide continuous cold-water biological filtration — the ideal scenario. However, Autumn/Winter Prep is specifically designed to work even if the filter and pump are shut down for winter. In that case, the bacteria will colonize the pond bottom (benthic zone) and continue digesting organic waste where it settles. Either approach works; running the filter at reduced flow (rather than complete shutdown) is generally preferred for pond health in climates that permit it.
