Remember, the water from your pond needs to pass through the UV before it enters the BioFilter, so why not install it on top of your filter box? (RetroFit UVs are designed to replace the existing BioFilter lid)

Clean your quartz sleeve every three months to ensure maximum performance from your UV system.

When selecting your UV make sure that it is compatible in performance with the BioFilter it will be used with.
 

During the spring and summer months algae bloom causes green water to appear in your pond.
The installation of a UV Steriliser is the only sure way to deal with this unsightly problem.
The way a UV works is that pond water is passed through a chamber containing an ultra violet lamp.
The algae cells present are penetrated by the light, destroying their ability to multiply and causing them to form clumps which can be captured in the Trident TOPFLOW unit. The mild sterilising effect of the UV will also assist in the reduction of harmful pond bacteria.
