Directions For Use:

Switch off UV steriliser until course of treatment is complete. Tighten cap and mix well. Use cup supplied to measure the correct dose. Add water to a clean watering can, then add Ariflavine & Malachite Green Premix. Gradually sprinkle across the surface area of the pond over a 1 hour period.

Once the course of treatment is complete monitor your water parameters regularly and add good bacteria to restart your filters.
