ClearLake Cold Water Clarifier | 8 & 24 lb | Below 52°F

ClearLake Cold Water Clarifier When the water drops below about 52°F / 11°C, ordinary pond bacteria slow down. Leaves, twigs, and fish waste still settle and stain the water. This ClearLake formula uses cold-tolerant strains in water-soluble bags so you can keep treating the water column through fall, winter, and early spring. Same job as ClearLake Pond & Lake Clarifier — suspended organics, off-color water — different temperature range. Product When to use ClearLake Pond & Lake Clarifier Water above about 50–52°F ClearLake Cold Water Clarifier Water below about 52°F ClearLake Muck Eliminator Tablets Bottom sludge, any season the label allows Switch products when the thermometer says so. Do not run both clarifiers as a “double dose” in the same week unless you have a reason. This is not an algaecide, not a dye, not a flocculant, and not a heater. Results vary with temperature, ice cover, aeration, and how evenly you spread the bags. Sizes and coverage (when dosed as directed): Same acre rates as the warm-water bags. Initial: 6 lb per surface acre Maintenance: 2 to 3 lb per surface acre every 2 weeks 1 bag = 8 oz Pond surface Initial Every 2 weeks ¼ acre 1.5 lb (3 bags) 0.5–0.75 lb ½ acre 3 lb (6 bags) 1–1.5 lb 1 acre 6 lb (12 bags) 2–3 lb 8 lb covers a ½-acre first dose or several maintenance rounds. 24 lb is the season bucket for about 1 acre. How to use: Confirm water is in the cold range (below about 52°F). Figure surface acres. Do not guess. First treatment: 6 lb per acre. Toss bags in a grid. Do not pile them in one spot. Repeat 2–3 lb per acre every 2 weeks while the water stays cold. Keep some circulation if you can. Bacteria still need oxygen. Do not dose into a solid ice sheet with no open water. For Southern California ponds: You may only need this product for a short stretch of cool weeks, or after a heavy leaf drop. When daytime water is back in the 50s and rising, switch to the regular Pond & Lake Clarifier. Fish and plants: Intended for ponds and lakes with fish and plants when used as directed. Follow the label. What this is not: Not the warm-water ClearLake clarifier Not muck tablets Not a winter algae killer Not a substitute for netting leaves before they sink Need help choosing cold vs warm clarifier for your pond? Contact Us FAQ Can I use this in summer? It is made for cold water. In warm weather buy Pond & Lake Clarifier. Will it work under ice? Only if you have open water to throw bags into and some movement. It will not treat a sealed frozen pond. Same rate as the green-label clarifier? Yes. 6 lb/acre first, then 2–3 lb every two weeks. The difference is the temperature, not the math.
