Aquarium And Pond UV Clarifier Filters

If you want to prevent unwanted algae build-up and remove harmful bacteria from the water where your pet fish live, using a UV clarifier in your pond or aquarium is an effective way to go about it. A UV pond clarifier stops water going murky or green so that you can enjoy your water feature as intended. Alongside this benefit, a UV clarifier can also inhibit harmful bacteria and pathogens in the water, therefore helping to stop the spread of fish diseases. 

At Finest Filters, you’ll find a suitable UV pond clarifier or aquarium UV steriliser for your specific needs. Our popular standard size UV Steriliser/Clarifier is available in 18w, 24w, or 36w options. These models are suitable for freshwater aquariums and ponds, but not saltwater environments. If you’re looking for a larger UV pond steriliser, we have a UV Steriliser/Clarifier for sale in 55w, 72w, and 110w varieties. These models come with a 5 metre cable and fittings included. To use a UV pond clarifier, you’ll also need to have a correctly fitting pond hose.

There will come a time when you need to replace the UV pond bulbs in your clarifier or fish tank UV light. We have a large selection of replacement bulbs, with various fittings, including PLL, PLS, and linear types. Double check the model of your UV steriliser lamp to ensure you get the right replacement bulbs. Look for your UV clarifier or bulbs below, or contact us for more information on selecting the right model for your aquarium or pond.
