Ultraviolet Clarifiers

At the heart of UV Calirifier unit is an ultraviolet lamp housed within a quartz sleeve.  As water is constantly pumped from the pond through the unit, the UV emitted from the lamp destroys the single-celled algae which causes the pond water to turn green.  With constant use the pond water will remain crystal clear


At Angel Koi we can source almost any variation of UV and the items below are simply illustrative of the range we carry.  Dont see what you need, please contact us

Amalgam Submersible UVC

Evolution Aqua

The new Evolution Aqua evoUV deliver a more efficient and more economical performance than before thanks to their new design.

The new range includes completely redesigned 30 Watt and 55 Watt models, a new 15 Watt and 25 Watt model perfect for use on the smaller garden pond, along with a 75 Watt version.


The top end 75 Watt model is designed for ponds up to 75,000 litres. The highly efficient ballast and high output 75 Watt UV bulb provides a more economical option than a traditional 110 Watt UV due to the greater UV contact time offered by the 1.2 metre bulb – ultimately saving you money!


The evoUV pond clarifiers are manufactured in house by Evolution Aqua, continuing our long tradition for manufacturing exceptional pond filtration equipment right here in the UK.

evoUVs ensure that your pond water will have amazing clarity, by killing the single cell algae that causes green water.
