What are pond UV lights and do you need one | Warehouse Aquatics | Middlewich

Ponds need constant upkeep to keep fish and other pond life healthy. One way to maintain your pond is to invest in a pond UV light (also known as a UV filter or a UVC clarifier). A UV filter can help you control algae and green water, which is ideal for pond keepers who are hoping to achieve crystal clear water.

What are pond UV filters?

UV filters aren’t like other filters as they don’t directly remove debris. Instead, these UV lights work when pond water pumps through their light path, exposing algae to high levels of ultraviolet light. This ultraviolet light destroys algae DNA, killing the algae. The light also causes the algae to clump together, which makes it easier for you to remove it from the pond. 

Although UV filters are effective, they do only work on single-celled alga. This means they won’t combat blanketweed. You can use a separate blanketweed treatment for this.

All-in-one pond filters

You need a pond filter as well as a pond UV light to keep your pond water clear and healthy. That said, when it’s time to replace your pond filter, you can opt for a filter that comes with a UV light and additional filter media. These all-in-one pond filters are ideal for both filtering and clarifying your water.

Remember to replace your UV bulb every 12 months (or as advised in the bulb manual) before they lose their effectiveness.
