Evolution Aquas innovative Evo UV range comprises of three sizes of UV Clarifier for use in garden ponds, and since the moment of their release they have quickly become firm favourites with pond keepers all over Europe and beyond.  You can choose from either the Evo 15, Evo 25, Evo 30, Evo 55, covering a wide range of pond sizes from your little wildlife pond strait to your large koi ponds.

Larger intensities of UV light causes free floating algae blooms to fuse together into larger particles and die, allowing them to be captured by the media in your pond filter and be broken down, leaving you with cleaner water.  They have unique design that gives less head loss than other manufacturers models, saving energy costs by negating the need for a more expensive pump.

There are quite a few on the market now, however the EVO range has developed a reputation for reliability, efficiency and an ability to get great results - near perfect water clarity.
