Aquarium UV sterilisers and inline clarifiers

Browse Eheim Reeflex UV and WiFi-controlled ReeflexUV+e models, Fluval inline UVC clarifiers, Dymax UV-Flo and Blue Planet aquarium units. Dymax UV-Flo 5W options are listed for 12/16mm and 16/22mm hoses. The Fluval FX UVC inline clarifier includes hose adapters for 25mm to 16mm connections. Check your filter, plumbing and recommended flow rate before selecting a unit.

Pond UV clarifiers and filter systems

The pond range includes Pond One Clear Tec, Blagdon MiniPond and Pro UVC, and Eheim CLEARUVC units. Fluval Jet Clear and Pressure-Flo systems combine filtration with UVC clarification. Compare the manufacturer's pond-volume guidance, fish-loading recommendations and pump requirements for your setup.

What does a UV unit help with?

UV clarification targets suspended algae that pass through the unit and contribute to green water. It does not directly remove algae attached to rocks, plants or aquarium glass. Performance depends on the selected model, water flow, exposure time and lamp condition. Use the manufacturer's guidance for your intended purpose rather than choosing by wattage alone.

Replacement bulbs, quartz sleeves and fittings

Find replacement UV lamps, quartz sleeves and selected fittings for compatible systems. Eheim Reeflex replacement bulbs include two-pin and four-pin versions, so check the connection type as well as the model and wattage. Follow the maintenance schedule for your particular unit: lamp service intervals differ between conventional UV bulbs and Fluval CCFL models. Confirm the exact part match before ordering, and check individual listings for any additional delivery charges.
