The Tetra EasyCrystal FilterBox is used for mechanical, chemical and biological water treatment in aquariums and is intended for use in freshwater aquariums.

Thanks to its intensive mechanical, biological and chemical filtering, the Tetra EasyCrystal FilterBox ensures crystal-clear and healthy water thanks to the innovative filter cartridge. An additional compartment enables the inconspicuous storage of a heating element (adjustable heater not included - we recommend the precise Tetra heater). In mechanical filtering, a double-layer filter fleece reliably removes even the smallest floating particles. The white side is used for rough pre-filtering, the green side for fine filtering. Bio-Grid with an extra-large surface for the settlement of useful cleaning bacteria through the filter grid "EasyCrystal" is used for biological filtering. Special activated carbon is used to eliminate water discolouration and unpleasant smells and thus chemically clean the aquarium water. Cleaning the Tetra EasyCrystal FilterBox is extremely easy: the filter cartridges are replaced every 4 weeks. No more washing out of the filter medium and wet hands are a thing of the past! The powerful magnetic turbine enables a high water flow, the compact housing saves space. Thanks to the flexible suction cups, the internal filter can be attached flexibly and securely. The filter media are available as spare parts. The Tetra EasyCrystal FilterBox is TÜV / GS tested, CE certified and has a 2 year guarantee.

Tip: Filter cleaning and changing always mean a loss of filter bacteria. With Tetra Bactozym, the bacterial activator, you can compensate for this loss in no time.
