This 18 watt UV clarifier is a quality German product.
It can take up to 3500 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 20000 litres, less if the pond has lots of big fish!
