HW 15w UV device (model 500)
Aquarists know the problems: Despite careful care, their fish are swimming in "turbid water" or their long-awaited, successful reproduction of their fish fails because of fungal growth on the fish eggs...
The reason for this is usually contamination of the aquarium water by fungal spores, bacterial micro-organisms, water clouds or floating algae.
Using a hw® UV Water Sterilizer prevents their spreading safely and without harmful side effects. In the mini ecosystem aquarium, the bacterial load is many times higher due to the very limited water volume compared to natural environments. Without the use of a hw®-UV-Water Sterilizer, the load of unwanted micro-organisms will steadily increase, leaving the natural balance completely behind. With the installation of a hw®-UV-Water Sterilizer you can ensure a microbiological balance in your aquarium system and near natural conditions.
hw®-UV-Water Sterilizers are a special construction that has proven itself more than 100,000 times in research institutions, in the commercial sector and in ambitious hobby aquarists.
Due to the extremely large contact surface with the direct UV-C radiation source in combination with a small layer thickness (3 to 4 mm) of the water to be irradiated, so intensive irradiation is achieved that would otherwise only be achieved by devices with wattages almost twice as much. high.
In a closed radiation chamber, the aquarium water is led past an artificial, very intensive UV-C radiation source. The bacterial micro-organisms, cloudy water and floating algae in the water are so intensively irradiated with UV-C radiation that they are immediately killed or are no longer capable of cell division and death.
The special glass jacket used acts as a UV-C radiation reflector, which reflects the UV-C radiation back into the radiation room. In this way, the intensity of the radiation is significantly increased again and an increased power output is achieved. At the same time, the special glass jacket allows a precise function check of the UV-C burner and a status check of the radiation room.
The visible light that penetrates to the outside is completely filtered and completely harmless (corresponding to the light emission of a normal neon fluorescent tube…).
When UV-C radiation occurs, sterilized water from the hw® UV Water Sterilizer constantly mixes with germ-rich water from the aquarium (nitrification bacteria in the filter and in the bottom of the aquarium are not damaged by UV-C radiation) . It is therefore not a complete "disinfection" of the entire aquarium water, but a strong germ reduction (maximum germ reduction in the entire aquarium system approx. 98%) of the aquarium water.
This is extremely important and necessary, because the germs left in the water (approx. 2 to 3%) maintain the fish's antibody production against pathogens and strengthen their immune system.
The effective protection against germ contamination, bacterial water turbidity and floating algae in marine and freshwater aquariums.
