## Summary description

ZOOLOGIA Bio Square sponge 15 x 7 cm is a biological filtration sponge designed for aquarium use. The rectangular 15 by 7 cm foam provides mechanical and biological filtration by trapping debris and supporting beneficial bacterial colonization. Suitable for use in internal and external filter chambers, sponge filters, or as replacement media to improve water clarity and biological stability.

## Long description

ZOOLOGIA Bio Square sponge 15 x 7 cm is a rectangular aquarium filtration foam designed to provide both mechanical and biological filtration. The 15 x 7 cm size fits a variety of internal and external filter chambers and sponge filter housings, capturing suspended debris while offering a porous surface for beneficial nitrifying bacteria to colonize. The open-cell foam structure promotes water flow and gas exchange, contributing to improved water clarity and biological stability in freshwater and adequately filtered planted aquaria.
Advantages
The Bio Square sponge combines mechanical debris removal with a large surface area for bacterial growth, reducing organic load and supporting the nitrogen cycle. Its rectangular shape and standard dimensions allow easy cutting or stacking to match different filter housings. The foam is durable and resilient under typical aquarium flow conditions and can be rinsed and reused multiple times without significant degradation when maintained properly.
Suitable for
 Internal filter chambers in small to medium aquaria
 Sponge filters for biological filtration and gentle flow
 External canister pre-filters or media compartments
 Replacement or upgrade of existing mechanical/biological media
Key specifications
 Shape: Rectangular foam block
 Dimensions: 15 x 7 cm
 Material: Open-cell filtration foam suitable for bacterial colonization
 Filtration function: Mechanical trapping of particles and biological surface for nitrifying bacteria
 Compatible environments: Freshwater aquaria and planted tanks with standard filtration setups
How to use
Rinse the sponge under aquarium water or dechlorinated water before first use to remove loose particles. Insert the Bio Square into the intended filter compartment, sponge filter housing, or pre-filter slot, ensuring water flows through the material for effective trapping and bacterial colonization. If necessary, trim the foam with scissors to fit non-standard compartments or to increase flow by creating additional channels. Do not use detergents or hot water, as these can damage the foam and remove beneficial bacteria.
Usage recommendations
Perform routine maintenance by gently rinsing the sponge in removed aquarium water during water changes to preserve beneficial bacteria while removing trapped debris. Replace the sponge only when it shows signs of permanent compression, tearing, or irreparable biofilm saturation; otherwise periodic cleaning will maintain performance. Avoid sterilizing methods that eliminate beneficial bacteria.
