API POND ALGAEFIX Algae Control 64oz Bottle (FF-169D)

Clear pond water starts with a proven algae solution

API POND ALGAEFIX tackles common algae problems in ponds and water features while remaining safe for fish, aquatic plants, wildlife, and pets when used as directed. The result is water that often looks clearer under sunlight, with fewer green blooms and reflections returning to a natural shimmer. Each 64 oz bottle is designed to treat up to 19,200 gallons, offering a practical option for mid to larger ponds and koi ponds.

What it treats

• Green water algae such as Chlorella
• String and hair algae including Cladophora
• Blanket weed algae such as Oedogonium

Key benefits you may notice

• Faster control of existing blooms and prevention of new ones when used as directed
• Safe for fish and plants and compatible with pond ecosystems

Typical maintenance routines are simple to follow and can help keep water looking clear with less manual effort. Start with thorough mixing into the pond and even dispersion. Reapply every three days until algae are controlled, then switch to a weekly maintenance dose to sustain clarity.
