Using an ultraviolet clarifier in your pond will ensure that your pond water stays clear of algae. Simply place the UV clarifier in the water circuit ideally up stream from the filter and eliminate green water..
UV clarifiers cause the algae in your pond to clump together to become large enough to be removed by the filter.
Pond type and pond water volume determine the capacity of the UV clarifier required.
Allow 8 to 10 w per 1000 gallons with a low fish stock( assuming the filter recirculates the pond water volume once every 2 hours) with a high fish stock the UV capacity will double.
