This OASE 55 watt UV clarifier is a quality German product.

It can take up to 8500 litres per hour.  

We recommend this product for people who already have biological filtration, but are still experiencing green water due to the pond’s sun exposure.  

For ponds up to 30000 litres, less if the pond has lots of big fish!
