Description
UV-C water clarification for freshwater and marine aquariums
A hw UV clarifier can reduce bacterial cloudiness, suspended algae and the microbial load in the water passing through it. It supplements aquarium maintenance and filtration. You should also investigate the causes of cloudiness or disease.
How UV-C treatment works
Aquarium water flows past a UV-C source inside a closed irradiation chamber. The radiation can kill microorganisms or inhibit their reproduction. A water layer of approximately 3–4 mm supports irradiation of the passing water.
Performance depends on the flow rate, water quality, condition of the special glass jacket and UV-C output of the lamp. Follow the model-specific flow data and operating instructions. Electrical power consumption alone does not allow a direct comparison of the disinfection performance of different devices.
Effect in the aquarium and limitations
Only water passing through the clarifier is treated. It then mixes with the aquarium water again. Microorganisms attached to the substrate, filter or decorations are not directly irradiated. A UV clarifier therefore does not sterilise the entire aquarium or remove dissolved pollutants. Attached algae are not directly affected by irradiation inside the device.
Safe operation and maintenance
Operate the device only when fully assembled, with an intact special glass jacket, and in accordance with the instructions. UV-C radiation can damage eyes and skin. Switch off and disconnect the device from the power supply before maintenance. Visible light allows a function check but does not demonstrate the remaining UV-C output.
Check the flow and condition of the device regularly. Clean and replace components as specified in the operating instructions. For help with selection, see the overview of hw UV clarifiers.
