UV-C Sterilizer for Fresh, Sea, and Lake Water Sera's UV-C systems are versatile and highly effective. They are ideal for use in both ponds and aquariums. UV-C radiation is not naturally found on Earth; it originates solely from outer space. As a result, no organisms have evolved to withstand this intense radiation, including pathogens like bacteria, viruses, fungi, parasites, and even the reproductive stages of filamentous algae. This is where the UV-C system excels, enhancing the health and well-being of aquarium inhabitants when utilized during filtration. It effectively reduces bacterial water cloudiness and green water in ponds. Within these systems, water flows through a chamber where it is exposed to UV-C radiation for a brief duration. The unit features a UV-C emitting lamp, safeguarded by a premium silica glass tube through which the water circulates. Water enters through a hose connector and exits via another connector on the opposite side. The adjustable adapter accommodates hoses of various sizes. Changing the highly efficient PL UV-C lamp is straightforward. The connector ends with hose fittings are rotatable, facilitating the shortest hose connection possible. The systems come in various capacities to meet your specific requirements (see overview). They connect to a compatible, powerful pump using a hose. Sera UV-C systems are primarily designed with energy-efficient lamps and a smoothly operating electronic ballast. Sera UV-C System 24W (UV-C Cleaner): effectively removes all types of floating algae (cloudiness, green water) without relying on chemicals curtails the growth of filamentous and other algae minimizes the risk of diseases and bacterial cloudiness in the water robust yet energy-efficient UV-C cleaner with universal fittings for different filters and pumps. Inflow and outflow of irradiated water and hose connections facilitated by variable connections. Included in the kit: 2 pieces of direct variable connection: ф 20 / 25 / 32 / 40 mm (¾” / 1” / 1¼ “/ 1½”) The 24 W and 55 W UV-C systems come with a 10-meter cable. Recommended Flow Rates: for aquariums: 1000 – 2000 litres/hour for ponds: 2000 – 4000 litres/hour The UV-C System requires a pump to operate. Neither the aquarium's inhabitants nor the beneficial nitrifying bacteria in the filter are harmed by UV radiation. A suitable pump must be chosen to match the recommended flow rates.

This makes the UV-C system particularly effective in enhancing the health and condition of aquarium inhabitants when utilized during filtration. It effectively reduces bacterial cloudiness and green water in ponds. Additional Product Information  Within these systems, water is briefly exposed to UV-C radiation. The unit features a UV-C emitting lamp safeguarded by a high-quality silica glass tube, allowing water to flow around it. Water is drawn in through one hose connector and exits through another on the opposite end. The adjustable adapter facilitates the connection of hoses of various sizes. The highly efficient PL UV-C lamp is easy to replace. The end pieces with hose connectors can rotate, ensuring the shortest possible hose connection.
