Colombo BiOx is a pond treatment formulated to control blanket weed while improving overall water quality. Using active oxygen, it works quickly on contact with water to support a cleaner and healthier pond environment. It is suitable for regular use and safe for both fish and aquatic plants when applied as directed.

Key Features:

• Helps prevent and control blanket weed naturally
• Releases active oxygen on contact with water
• Supports biological filtration by improving oxygen levels
• Aids in breaking down sludge and organic waste
• Safe for fish and pond plants
• Suitable for ongoing weekly maintenance

By increasing oxygen levels, Colombo BiOx helps beneficial filter bacteria work more effectively, while also making it easier for fish to absorb oxygen. Regular weekly dosing keeps pond water clearer and reduces the conditions that allow blanket weed to develop.

Dosage:

Weekly: 15 ml per 500 litres of pond water
Do not pour directly onto plants
Tip: For more persistent blanket weed, use alongside Colombo Algisin, then maintain results with regular BiOx use.
