Mix Blue Lagoon with 5-10 litres of water in a suitable container and distribute evenly over the pond. When the water colouration fades, reapply half the dosage (approx. every 6 weeks).
For best results start in spring and reapply regularly. The deeper the pond is, the more effective and longer lasting it is. Pond water treated with Blue Lagoon is harmless to all pets (dogs, cats) and birds.
