• Algae growth control for ponds, water gardens, and fountains
• Effectively controls Chlorella, Cladophora, & Oedogonium algae
• Works fast to keep ponds, water gardens, & fountains clean & clear

Liquid algae growth control for ponds with plants and fish. ALGAEFIX effectively controls these types of algae: Green or "Green water" algae (Chlorella sp.), String or Hair algae (Cladophora sp.), and Blanketweed (Oedogonium sp.) in ornamental ponds. Fast-acting solution keeps ponds, water gardens, and fountains clean and clear. Will not harm fish and plants when used as directed. 8 ounces treats 2,400 gallons.

For synthetically lined pond and fountain use only, where all water is contained without any outflow.

Caution: Do not use with freshwater crustaceans, including: shrimp, crabs and lobsters.

Active Ingredient: Poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride]: 4.50% Other Ingredients: 95.50%

WARM WEATHER CAUTION: Before using, make certain that the pond has vigorous aeration, i.e. a fountain or aeration device to avoid fish loss due to low oxygen levels. When algae is controlled and removed by the filter or settles to the bottom of the pond, the oxygen level may drop to harmful levels if adequate aeration is not provided. In warm weather, pond water carries much less oxygen. Therefore, when using during warm weather and high water temperatures, vigorous, 24-hour aeration is required for the duration of the treatment. Do not shut off pond pumps and aeration devices at night.

To ensure accurate dosing, determine pond volume before use. Add 1 teaspoon (5 ml) for each 50 US gallons of pond/fountain water or 1/4 cup (60 ml) for each 600 gallons of pond or fountain water. Thoroughly mix into pond water by adding near the pump outflow, waterfall, or aeration device. It can be mixed in a bucket of pond/fountain water and dispersed evenly around the pond. Repeat dose every 3 days until algae is controlled. Be prepared to siphon out dead filamentous algae. Once algae growth is under control, add one dose per week. Weekly treatments will control algal growth and reduce pond maintenance.

Caution: Do not use with freshwater crustaceans, including: shrimp, crabs, and lobsters.
