## Long description

Tetra EasyCrystal FilterBox 600 is an internal aquarium filter designed for freshwater tanks with a capacity of 50–150 L. It combines mechanical, biological and chemical filtration in a compact unit with integrated media compartments and a heater slot. The device supports water circulation and oxygenation while maintaining clarity and reducing odors, making it appropriate for routine maintenance and regular water purification in medium-sized aquariums.
Advantages
The integrated design of the Tetra EasyCrystal FilterBox 600 allows fast and dry cartridge replacement, limiting contact with used filter media. Mechanical filtration with double-layered floss pads captures fine particles, while the BioGrid provides a large surface for beneficial bacteria to develop. A layer of activated carbon handles discoloration and unwanted odors. The compact form factor saves space inside the tank and the unit is TÜV/GS tested with a manufacturer's two-year guarantee.

How to use
Install the Tetra EasyCrystal FilterBox 600 inside the aquarium according to the manufacturer's instructions, positioning it to ensure adequate water flow through the media compartments and, if needed, slide in the heater into the dedicated compartment. Prime the filter as instructed and connect the power supply. Replace the filter cartridge or individual media elements at regular intervals: remove the cartridge using the dry-change system, dispose or rinse media as recommended, then insert fresh media ensuring correct orientation. Clean surfaces and intake areas periodically to maintain flow and filtration efficiency.
Usage recommendations
For stable water parameters, combine regular partial water changes with scheduled media replacement and occasional gentle rinsing of biological media in aquarium water to preserve beneficial bacteria. Avoid using tap water with chlorine for rinsing biological components; use dechlorinated water instead. Monitor flow and water clarity after installation and after each maintenance operation.
