UV Lamp Replacement for Ultra violet clarifiers that are used in ponds to eliminate water born floating algae which turns the pond water green and starve it of oxygen. Algae as well as plants compete with the fish for the oxygen available within the pond at night. This oxygen is only produced during the ‘daytime’ cycle of photosynthesis. Reducing the algae within the pond will allow the fish to breathe easier minimising stress and the risk of disease.
