Colombo Algadrex is a fast-acting green water treatment designed to clear pond water quickly and restore visibility. It works by clumping together floating algae so they can be removed via filtration, netting, or by settling at the bottom, helping improve overall water quality and light levels for plants.

Key Features

• Fast-acting formula clears green water, often within one hour
• Targets free-floating algae that cause cloudy green ponds
• Improves water clarity, light penetration, and oxygen balance
• Clumps algae for easy removal via filter or pond net
• Includes test strip to check KH levels before use
• Suitable for a range of pond sizes with clear dosing guidance
• Available in 500ml, 1L, and 2.5L sizes

Dose accurately based on pond volume: 500ml treats 5,000 litres, 1L treats 10,000 litres, and 2.5L treats 25,000 litres. Always check that KH is at least 6 before use and follow preparation steps, including switching off UV, ozone, and air systems during treatment. After clearing, ongoing maintenance helps keep water clean and balanced.
