## Summary description

Tetra EasyCrystal filter cartridge pack containing 3 replacement cartridges for compatible EasyCrystal aquarium filters. Designed for mechanical and biological filtration in small to medium home aquariums, these cartridges help remove debris and support beneficial bacteria. Use as periodic replacements to maintain water clarity and filter performance.

## Long description

Tetra EasyCrystal filter cartridge pack contains three replacement cartridges designed for use with compatible EasyCrystal aquarium filters. Each cartridge combines mechanical, biological and chemical filtration media to remove visible debris, reduce cloudiness and support the development of beneficial bacteria in small to medium home aquariums. Cartridges are manufactured for quick, dry replacement to maintain continuous filter performance and clear water.
Advantages
The cartridge pack provides a complete filtration stage in a single, easy-to-replace unit. Double-layered filter floss removes coarse and fine particles, while activated carbon reduces discoloration and odours. The integrated design supports biological filtration by providing surface area for nitrifying bacteria, helping to stabilise water parameters between regular maintenance intervals. Changing cartridges every four weeks preserves flow rate and filtration efficiency without the need to handle or rinse the filter media.
Suitable for
 Small to medium freshwater home aquariums using Tetra EasyCrystal filters
 Routine monthly cartridge replacement to maintain water clarity
 Aquariums where quick, dry cartridge changes are preferred to reduce mess
Key specifications
 Pack contents: 3 filter cartridges
 Filtration stages: mechanical (double-layered filter floss), chemical (activated carbon), biological (surface for beneficial bacteria)
 Mechanical layer: white coarse pre-filter side + green fine filter side
 Recommended replacement interval: approximately every 4 weeks for best results
 Compatibility: designed for Tetra EasyCrystal series filters (check individual filter model alignment)
How to use
Turn off the aquarium filter and remove the filter cover according to the filter manufacturer's instructions. Extract the used cartridge and dispose of it responsibly. Insert a new Tetra EasyCrystal cartridge so that the white coarse side and green fine side align as required by the filter housing, then replace the cover and restart the filter. There is no need to rinse the cartridge before installation; follow regular monitoring of water clarity and flow to determine optimal replacement timing.
Usage recommendations
For consistent performance, replace cartridges every four weeks or sooner if flow rate or water clarity declines. Do not attempt to wash and reuse activated carbon cartridges; replace them to maintain chemical filtration. When performing water changes or cleaning, avoid removing established beneficial bacterial colonies from other filter components to preserve biological stability.
