API Algaefix

Product overview

Keep aquarium water clear and cut down on maintenance with API Algaefix Algae Control. Algae can quickly cover glass, coat decorations, crowd live plants, and turn the water green.

This liquid treatment targets active algae. Used as directed, it helps clear existing outbreaks and can be used weekly to help stop new growth.

For freshwater use only.

Key features

• Controls common aquarium algae, including green-water blooms, string or hair algae (Cladophora), staghorn, and brush algae.
• Clears algae from surfaces such as glass, gravel, ornaments, and slow-growing plant leaves.
• Safe for freshwater fish and live plants when used at the recommended dose, including tropical community fish, cichlids, and goldfish.
• Less scraping and scrubbing when used as part of regular tank care.

Dosing and instructions

Always double check dosage and directions on product packaging

• Standard dose: 1 ml per 38 litres (1 ml per 10 US gallons) of aquarium water.
• Active outbreaks: Repeat every 3 days until the algae is under control.
