Pond UV Sterilisers

UV clarifiers and sterilisers to beat green water.

Buying guide

A UV unit is the straightforward answer to green water, clearing the free-floating single-celled algae that cloud a pond and leaving the water bright again. Contact time is what makes it work, so match the unit to your pump's flow rate for the full effect. Fitted after the pump and before or within the filter, the treated algae clump together for the filter to catch. Choose by pond volume and flow rate, and the wattage follows naturally.

    How Do I Choose a Pond UV Steriliser?

    The best steriliser for your pond will depend on the size of your pond, and therefore the volume of water.

    Our Pond UV Steriliser / Clarifier Stainless Steel provides no less than 110 W of SSUV and harnesses a stainless steel design that is up to 30% more effective than plastic.

    This super tough model can manage ponds of up to 115,000 litres and is suited to the largest of areas with a two-year warranty included as standard.

    Another best-seller for smaller ponds and aquariums is our 9 W Pond UV Steriliser. This compact model uses a unique helix construction, which spins the water delivering more extensive UV exposure for faster, more thorough sterilisation.

    Also suitable for both marine and freshwater ponds and aquariums, the 9 W model also offers a triple inlet/outlet design, adaptable for waterfall features, and can manage water up to 4,000 litres in volume.

    We are proud to supply our very own AllPondSolutions Pond UV Steriliser range, leveraging our years of experience in professional pond care to offer outstanding value and unbeatable performance.
