Evolution Aqua’s pond UV clarifiers have been completely re-designed for 2021, to deliver even greater performance and improved serviceability. Our range of six evoUV pond clarifiers are made using the very latest technology and design techniques, ensuring there is even water flow through the unit, and optimum ultraviolet light penetration.

One new feature is the ease of the serviceability of the evoUV. Changing bulbs, quartz sleeves or replacing a failed ballast are quick and simple to do.

The evoUV is simple to install, with universal mounting plates allowing you to fix the unit
horizontally or vertically, or at any angle you choose.

The evoUV range of clarifiers have been designed to clear green water which is caused by single celled green algae and prevent it from returning. They will work alongside many different filtration systems but when used alongside Evolution Aqua’s pond filtration systems, the evoUV will help to deliver crystal clear and healthy pond water. 

Your evoUV professional quality UV can be connected to your pond pump and filter with flexible hose using the stepped hosetails provided, or you can install the unit using hard pipe.
