ClearLake Pond & Lake Clarifier These are 8 oz water-soluble bags of concentrated beneficial bacteria from ClearLake (ProLake / Keeton). Toss them out in a grid. The bags dissolve and the bacteria work on suspended organic material in the water, which is what usually makes a pond look stained, dull, or “dirty” even when the filter is running. That is a different job from ClearLake Muck Eliminator Tablets. Tablets sink and work in bottom sludge. These bags work in the water you see. Use above 50°F (10°C). For colder water, use ClearLake Cold Water Clarifier instead. This product is not a dye, not a flocculant (that is a product like Accu-Clear), not an algaecide, and not a UV sterilizer. Results vary with temperature, aeration, fish load, and how evenly you spread the bags. Sizes and coverage (when dosed as directed): Label rates are by surface acre. Initial application: 6 lb per surface acre Maintenance: 2 to 3 lb per surface acre every 2 weeks 1 bag = 8 oz Pond surface Initial dose Maintenance every 2 weeks ¼ acre 1.5 lb (3 bags) 0.5–0.75 lb (1–1½ bags) ½ acre 3 lb (6 bags) 1–1.5 lb (2–3 bags) 1 acre 6 lb (12 bags) 2–3 lb (4–6 bags) Rough guide to which bucket to buy: 4 lb — small pond or a trial 8 lb — ½-acre start, or several maintenance rounds 24 lb — best cost per pound for about 1 acre through a warm season How to use: Use when water is above 50°F. Figure surface acres: length (ft) × width (ft) ÷ 43,560. Do not guess. First treatment: 6 lb per surface acre. Throw bags in a grid. Do not stack them in one corner. Repeat 2 to 3 lb per acre every 2 weeks.Keep aeration running. Bacteria work faster with oxygen. How this compares to our other water treatments: Product Where it works Form ClearLake Pond & Lake Clarifier Water column (cloudy / off-color water) Dissolving 8 oz bags ClearLake Muck Eliminator Tablets Pond bottom (sludge, docks, swim area) Sinking tablets Pure Bale Weekly water-column support Barley / bacteria gel API Pond Aqua Essential Tap water + ammonia / nitrite / nitrate Liquid conditioner Algae No-Mo Visible algae when the label allows Liquid treatment *You can use clarifier bags and muck tablets in the same pond. They are meant to be paired. Do not dump a full initial dose of everything on the same afternoon if fish already look stressed. Fish, plants, and swimming: Intended for ponds and lakes with fish, plants, and recreation when used as directed. Follow the label. Add air if fish show stress. What this is not: Not a copper or peroxide algae treatment Not a polymer flocculant that “clumps” particles overnight Not a substitute for a filter or UV on green water Not the cold-water version of this product Need help matching a bucket to pond size? Contact Us FAQ Bags or tablets — which do I want? Cloudy water you can see through the top: bags. Soft black muck on the bottom: tablets. Many ponds need both. Will this kill string algae? No. It works on organic haze in the water. Use UV plus an algae product for blanketweed. Can I use it below 50°F? This formula is for warm water. Ask for ClearLake Cold Water Clarifier if you list it later.
