Deltec Complete UV-C Steriliser units offer high-efficiency water clarification and pathogen reduction for both marine and freshwater aquariums. Designed for reliability and long service life, these units use high-output UV-C lamps to reduce harmful microorganisms, control algae blooms, and deliver visibly clearer water.

These Deltec UV-C sterilisers feature robust construction, secure end caps, and high-quality quartz sleeves for maximum UV transmission. They are well suited to reef tanks, fish-only systems, and aquaculture environments where water clarity and pathogen control are essential.

Important: Take care not to run the UV unit dry or with restricted flow. Always ensure the chamber is completely filled with water and all plumbing connections are secure before switching on the lamp.
