Overview
Green, cloudy water is usually a sign of free-floating algae or a bacterial bloom outpacing your filtration, and it's one of those problems that mechanical and biological filtration alone won't fix. The Cleartec UV 36W tackles it at the source, running your water past a UV-C lamp strong enough to irradiate algae cells and free-floating pathogens as they pass through, so they can't reproduce or continue clouding the tank.
At 36W, this is the step-up unit in the Cleartec range, built for larger systems or tanks running a heavier bioload where the smaller wattages just can't keep pace.
Key features
- 36W UV-C output for stronger clarification on bigger volumes of water
- Remote ballast on a long cable, so the electronics sit away from the wet area
- Multiple hose connection sizes for flexible plumbing into an existing return line
- Rotatable outlet to suit whatever orientation your plumbing needs
- Can be mounted on a wall or directly onto a filter box
Who it's for
Best suited to larger reef systems, or any tank that's struggling with recurring green water or algae blooms despite good filtration. It's inline, so it's built to run continuously as part of your plumbing rather than as a stand-alone gadget.
Setup & tips
- Plumb it in after your mechanical filtration so the water reaching the UV chamber is already clear of debris — clear water lets the UV dose every organism properly
- Don't oversize your flow rate through the unit; too fast a flow reduces contact time with the lamp and cuts effectiveness
- UV lamps lose output well before they stop glowing, so plan on replacing the bulb annually even if it still looks fine
- Keep the quartz sleeve clean — a build-up of grime or coralline algae on the sleeve blocks UV transmission into the water
