Natural Phosphate Removal for Ponds and Lakes
Scott Aerator Algae Shield is an all-natural, mineral-based water treatment designed to reduce algae growth in ponds and lakes. By removing excess phosphates and other nutrients that fuel algae blooms, Algae Shield helps restore water clarity and improve overall ecosystem health. A single treatment can eliminate up to 95% of available phosphates, making it an effective long-term solution for green water and recurring algae problems.
How Algae Shield Works
Algae Shield bonds with dissolved nutrients and converts them into insoluble particles that settle safely to the pond bottom. Once bound, these nutrients become biologically unavailable, helping prevent future algae growth. Its advanced silicate-enhanced formula performs effectively across a wide pH range, improves particle stability, and accelerates nutrient removal. Depending on application method and site conditions, Algae Shield can create a nutrient barrier that remains effective for up to 15 years.
Coverage and Application
Each 5-gallon bucket contains 22 pounds of Algae Shield and treats up to 500,000 gallons of water. By targeting eutrophication at its source, Algae Shield helps improve water quality, supports healthy fish populations, and promotes a more balanced aquatic environment.
See product label/documentation for complete application details.
-
Prepare
Mix product and water in a separate bucket at a 4:1 ratio (four parts water to one part product).
-
Pour
Transfer the mixed slurry into an applicator (such as a backpack sprayer or similar equipment).
-
Apply
Distribute slurry evenly across the surface of the pond or body of water.
-
Clean & Store
Rinse the applicator thoroughly, empty the rinse water back into the pond, and store the equipment for future use.
Application Tips
-
Do not mix the product directly in the applicator. Always use a separate container to prevent buildup and potential damage to your equipment.
-
Use the wind to your advantage. Wind can help distribute the mixture more evenly across the water’s surface. Remember that beneath the surface, the product will move diagonally with water flow.
-
Maintain the correct dilution ratio (4:1). Avoid over-diluting — the water’s surface should appear slightly red/brown during application, but not so dark that the mixture becomes thick or gummy in your applicator.
-
Equipment recommendation: For best results, use a trash pump or other continuous agitation equipment to keep the slurry well-mixed during application.
The application process will look different for every project, and some steps may need to be adjusted to fit your needs.
