How An Ultraviolet Pond Clarifier Works

Ultraviolet pond clarifiers (UV's) clear pond water by killing the microscopic algae that clouds the water. As the pond water is pumped through the ultraviolet pond clarifier, the algae is exposed to ultraviolet light killing the algae. Over a period of a few days the algae begins to decompose and gets trapped in your filter.

For an ultraviolet pond clarifier to work properly, two factors must be taken into consideration.

1. It must be sized correctly to the volume of your pond. If your pond is 3000 gallons, select a UV that is designed for at least 3000 gallons. Always choose a larger unit if possible.
2. The proper amount of water must be pumped through the UV. If your pump is too large and water is pumped through the UV too fast, the algae does not have enough contact time with the ultraviolet light and is not killed. If the water is pumped through the UV too slowly, the algae can reproduce in the pond faster than it is being killed by the UV.
