Keep your pond clean, clear, and healthy with Cloverleaf Blanket Weed Treatment, a trusted solution designed to eliminate and prevent blanket weed growth. Expertly formulated with a unique blend of minerals and enzymes, this treatment targets algae while remaining safe for fish, plants, and biological filtration systems.
Ideal for all types of garden ponds—from small wildlife ponds to large Koi ponds—this treatment ensures your pond stays visually appealing and supports a thriving aquatic environment.
What is Blanket Weed?
Blanket weed is a type of free-floating algae that can quickly cover your pond surface, including:
-
Blue-green algae
-
String algae
-
Filamentous algae
Excess algae blocks sunlight from reaching aquatic plants, stunts plant growth, and reduces oxygen levels, putting fish at risk. Cloverleaf Blanket Weed Treatment tackles this problem effectively.
How It Works
Cloverleaf Blanket Answer introduces beneficial bacteria into your pond. These bacteria:
-
Break down excess nutrients from fish waste, decaying plants, and dead algae

By restoring a balanced pond ecosystem, it improves water clarity and supports the health of fish and plants.
