Green water, free-floating algae, and waterborne pathogens circulate through even a well-filtered tank, since standard filtration doesn't kill what's suspended in the water column. Sicce UV-C Clarifiers control that with ultraviolet sterilization, in three aquarium sizes and a dedicated pond model.
Why UV-C Sterilization Helps
Mechanical and biological filtration handle particles and waste processing, but they don't neutralize free-floating algae cells or pathogens passing through the water. UV-C light exposure clears green water and reduces disease transmission risk in a way filtration alone can't.
Choosing a Size
- UV-C Clarifier 7W — Sicce's smallest aquarium UV sterilizer, controlling free-floating algae and pathogens that cause green water.
- UV-C Clarifier 9W — steps up sterilization capacity from the 7W, suited to slightly larger aquariums needing more UV throughput.
- UV-C Clarifier 13W Aquarium — the largest aquarium model, sized for bigger tanks needing more sterilization throughput.
- UV-C Clarifier 13W Pond — built for outdoor pond systems, using the same UV-C sterilization to control green water and pathogens at pond scale.
Setup Tips
- Size wattage to your water volume and flow rate through the unit — too fast a flow reduces UV contact time.
- Replace the UV bulb on schedule even if it still lights up, since output drops well before visible failure.
- Position inline with your filtration rather than as a standalone unit for consistent water passage.
