## Summary description

ZOOLOGIA Bio Square filter sponge, dimensions 15×10 cm, designed for aquarium filtration. Provides mechanical removal of debris and supports biological filtration by offering surface area for beneficial bacteria. Suitable for use inside hang-on, canister or internal filter compartments, for freshwater and community tanks to improve water clarity and biological stability.

## Long description

ZOOLOGIA Bio Square filter sponge 15×10 cm is a rectangular aquarium filtration medium designed to combine mechanical removal of particles with support for biological filtration. The sponge fits inside canister, internal and hang-on filter compartments and is intended for freshwater community tanks. Its open-cell structure traps debris while providing a large surface area where nitrifying bacteria can colonize, contributing to improved water clarity and biological stability.
Advantages
The sponge offers dual-function filtration: mechanical capture of suspended waste and a porous matrix for beneficial bacteria. Its standardized 15×10 cm dimensions make it compatible with many filter housings. The durable foam retains structural integrity during cleaning and use, and is washable for repeated service life. The neutral material does not alter water chemistry when used as intended.
Suitable for
Freshwater community aquariums
Placement in hang-on, internal or canister filter compartments
Pre-filtration to protect biological media downstream
Temporary or permanent mechanical/biological filtration upgrade
Key specifications
Shape: rectangular block
Dimensions: 15 × 10 cm
Material: open-cell foam for mechanical and biological filtration
Function: mechanical particle capture and support for nitrifying bacteria
Suitable water type: freshwater
How to use
Rinse the sponge briefly in dechlorinated water before first installation to remove any loose particles. Insert the sponge into the designated filter chamber so water flows through the foam evenly; position it as pre-filter or as part of the main filtration stack depending on your filter design. Monitor flow and check the sponge during routine maintenance. Clean by gently rinsing in tank water during water changes to preserve beneficial bacteria. Replace only when foam shows irreversible wear or damage that reduces filtration efficiency.
Usage recommendations
For consistent biological performance, avoid aggressive cleaning with tap water or detergents; use aquarium water for rinsing. Use the sponge in combination with other filter media—such as mechanical floss, activated carbon, or ceramic rings—to address specific water quality needs. Regular inspection and conservative cleaning will maintain both mechanical clarity and biological stability.
