Tetra EasyCrystal FilterBox 600 Internal aquarium filter with space for a heater. Provides crystal-clear and healthy water.

The innovative replaceable cartridge system allows you to clean the filter without wetting your hands.

Intensive mechanical, chemical, and biological filtration ensures crystal clarity and healthy water parameters:

• Mechanical filtration: the double-layer filter cartridges capture even the smallest impurities. The white part is responsible for pre-filtration, the green part for proper filtration.
• Biological filtration: filter sponge with a large surface area where beneficial bacteria can develop.
• Chemical filtration: special activated charcoal eliminates water cloudiness and unpleasant odors.

Compact design ensures the filter takes up little space in the aquarium. For use in aquariums with a capacity of 50 to 150 liters.
