🌡️ Works at 40°F — Start When Your Pond Thaws Psychrotrophic bacteria stay active in cold spring water. No need to wait for warm temperatures. Microbe-Lift Spring/Summer Cleaner – 8×2oz Packets (SKU 56265, MPN 10XSSX1) is the seasonal pond startup treatment that works when other bacterial products can't — starting at water temperatures as low as 40°F. Each box contains 8 pre-measured, water-soluble 2 oz packets of cellulase enzymes and psychrotrophic (cold-adapted) hyper cellulase-producing bacteria that accelerate the breakdown of leaves, twigs, dead vegetation, and organic sediment accumulated during fall and winter. The key distinction from year-round bacterial treatments like Microbe-Lift PL or API EcoFix: SSC uses psychrotrophic bacteria that are specifically adapted to reproduce and digest organic matter in cold early-spring water. The cellulase enzymes in each packet are specifically formulated to digest cellulose — the structural compound in leaves and plant material — which standard bacteria cannot efficiently break down. One 4-week spring treatment with SSC prepares your pond's organic baseline for the active season; follow with Microbe-Lift PL through summer for ongoing biological maintenance. SKU 56265 / MPN 10XSSX1 8 × 2 oz Packets Starts at 40°F Psychrotrophic Bacteria Cellulase Enzymes 4-Week Treatment Made in USA 🔬 The science behind SSC: Spring/Summer Cleaner packets contain two active components: (1) cellulase enzymes — specialized enzymes that break down cellulose, the structural molecule in leaves, twigs, and dead plant matter that accumulates over winter; and (2) psychrotrophic hyper cellulase-producing bacteria — cold-adapted strains that remain active and multiply at 40°F+, unlike warm-season bacteria that slow significantly below 50°F. The outer packet casing and bran carrier base are water-soluble; bacteria and enzymes are microscopic. When you see bran material dispersing in your pond, the treatment is working normally.

Psychrotrophic bacteria are biologically adapted to remain active and reproduce at temperatures as low as 40°F. SSC can begin treating your pond the moment ice-out occurs — weeks earlier than standard bacteria treatments. This head start matters: organic waste that sits untreated in cold spring water continues consuming oxygen and contributing nutrients as water warms. 🍂 Cellulase Enzymes — Leaf & Vegetation Digestion Cellulase is the enzyme that breaks down cellulose — the primary structural compound in leaves, twigs, dead plant stems, and winter vegetation debris. Standard beneficial bacteria cannot efficiently digest cellulose because they lack this enzyme. SSC's cellulase-producing bacteria generate cellulase continuously as they multiply in your pond water, targeting the specific organic compounds that accumulate over winter rather than just fish waste and nitrogen compounds. 💧 Water-Soluble Packets — Zero Measuring Each pre-measured packet's casing dissolves completely in pond water — just toss it in. The bran carrier base distributes into the water (this is normal and harmless), and bacteria and enzymes are released immediately. For targeted treatment under overhanging trees or in pond corners with heavy leaf accumulation, dissolve the packet first in a bucket of warm water, then pour around the specific areas for concentrated delivery where you need it most. 🌿 100% Natural — Non-Toxic, Non-Caustic Microbe-Lift Spring/Summer Cleaner is not a chemical — it contains only naturally occurring bacteria and enzymes. Safe for fish, koi, goldfish, aquatic plants, pets, and humans when used as directed. Non-caustic formulation means no risk of pH disruption from the product itself. All ingredients are manufactured in the USA. Compatible with all Microbe-Lift products and most other pond treatments. 📅 One-Month Treatment Protocol SSC is designed as a concentrated 4-week spring treatment — intensive enough to address the full winter's accumulation of organic matter in one application cycle. Apply according to the dosing table for your pond size, once per week for four consecutive weeks. The treatment accelerates decomposition of winter organic load before fish come out of torpor and begin generating new waste. After the 4-week SSC treatment, transition to Microbe-Lift PL for ongoing summer biological maintenance. 🇺🇸 Made in USA — Professional Grade All SSC ingredients are manufactured in the United States by Ecological Laboratories, Inc. (Microbe-Lift brand) — a professional-grade biological products company with decades of experience in pond and aquaculture microbiology. The psychrotrophic bacterial strains in SSC are the result of professional biological selection for cold-water performance — not generic shelf bacteria repackaged for the pond market.

Start as soon as your pond thaws in spring — SSC works at water temperatures as low as 40°F. If you have a pond thermometer, 40°F is the start signal. If not, simply begin once ice is fully gone from the pond. This early-spring timing is the whole point of SSC's psychrotrophic bacteria formulation: standard beneficial bacteria products (like Microbe-Lift PL) don't become effective until water reaches 50–55°F, leaving several weeks of early spring where organic winter waste is accumulating with no biological breakdown. SSC fills this cold-water window. What makes SSC different from regular pond bacteria products like Microbe-Lift PL? Three key differences: Cold-adapted bacteria: SSC contains psychrotrophic bacteria — strains that remain active and reproduce in water as cold as 40°F. Microbe-Lift PL uses warm-season bacteria optimized for 55°F+ water. Cellulase enzymes: SSC specifically contains cellulase enzymes that digest cellulose — the structural material in leaves, twigs, and dead plant matter. PL focuses on fish waste and nitrogen compounds. These two products target different types of organic material. Seasonal vs. ongoing: SSC is a 4-week intensive spring treatment. PL is designed for weekly or biweekly maintenance through the active season. Together, they form a complete annual biological program: SSC in spring (cold-water leaf/vegetation breakdown), PL through summer and fall (warm-water fish waste management). How do I use the packets? Do I need to measure anything? No measuring required. Two application methods: Direct toss: Simply drop the packet into the pond. The water-soluble outer casing dissolves within minutes, releasing bacteria and enzymes directly. The bran base distributes through the water — this is normal and harmless. Bacteria and enzymes are microscopic. Pre-dissolved (targeted): For ponds with heavy leaf accumulation in specific areas (under overhanging trees, back corners), place the packet in a bucket of warm water, allow it to dissolve completely, stir, then walk around the pond pouring near the problem areas for concentrated delivery. Apply one packet (or two, depending on your pond size — see dosing table) once per week for 4 consecutive weeks starting at spring thaw. I see brown material dissolving in my pond — is that normal? Yes — completely normal. The packet contains a bran carrier base that is clearly visible as it disperses in the water. The bacteria and enzymes themselves are microscopic. The bran is natural and harmless — it breaks down quickly in pond water and is safe for fish, plants, and wildlife. Can I use SSC with other pond treatments? Yes — Microbe-Lift Spring/Summer Cleaner is compatible with all other Microbe-Lift products and most standard pond treatments. The recommended combination is SSC (weeks 1–4 of spring) followed by Microbe-Lift PL (ongoing through summer). For maximum organic breakdown efficacy, you can also use both SSC and PL simultaneously during the transition period when water is warming from 40–55°F. As with any biological treatment, avoid using SSC immediately after treating with a chemical algaecide or antibiotic that might harm the bacteria. Wait 24–48 hours after chemical treatments before adding SSC. Why Buy from Pond Pro Direct?
