Colombo BiOx Blanket Weed treatment helps keep your pond clean by using active oxygen to naturally break down sludge, waste, and organic dirt. When Colombo BiOx comes into contact with pond water, it immediately releases active oxygen, which supports a healthier pond environment and improves the biological performance of your filtration system.
Pond filter bacteria need oxygen to break down waste effectively. By increasing oxygen levels, Colombo BiOx helps your pond filter work more efficiently while also making it easier for fish to absorb the oxygen they need from the water. Its natural oxidation power helps decompose sludge and reduce the build-up of biological waste, keeping pond water cleaner and fresher.
With regular weekly use, Colombo BiOx Blanket Weed treatment helps reduce blanket weed growth and supports better overall water quality. It is safe for fish and plants when used correctly, making it suitable for koi ponds, fish ponds, and garden ponds. This product is ideal for pond owners who want a simple and natural way to maintain cleaner water, reduce algae problems, and support healthy fish.
