## Summary description

ZOOLOGIA Bio round sponge, 12×7 cm, designed for biological filtration and routine cleaning in aquariums and terrariums. The rounded foam pad supports beneficial bacterial colonization for biological water treatment and helps trap debris and particulates. Suitable as a replacement or supplementary filter media and for gentle surface cleaning of aquatic and terrarium environments.

## Long description

ZOOLOGIA Bio round sponge 12×7 cm is a rounded foam pad designed for biological filtration and routine cleaning in aquariums and terrariums. The open-cell structure provides a protected surface for beneficial nitrifying bacteria to colonize, supporting natural biological water treatment. The sponge also traps suspended debris and particulates while allowing water flow, making it suitable as a replacement or supplementary filter media and for gentle surface cleaning of glass, acrylic and plastic surfaces in aquatic and terrarium setups.
Advantages
The sponge’s rounded shape and uniform pore structure ensure even water distribution and efficient capture of mechanical waste without significantly restricting flow. Its material is resilient and compressible, enabling easy fitting into a variety of filter housings and corners. Because it promotes bacterial colonization, the sponge contributes to stable nitrogen cycle processes and helps reduce ammonia and nitrite spikes when used as part of a biological filtration system.
Suitable for
Replacement or supplementary filter media in internal and external aquarium filters
Biological filtration in terrarium water features and paludaria
Routine surface cleaning of aquarium glass, acrylic or plastic without scratching
Pre-filtration to protect finer mechanical and chemical media
Key specifications
Shape: round
Dimensions: approximately 12 × 7 cm
Material: open-cell foam suitable for bacterial colonization
Function: mechanical debris capture and support for biological filtration
Compatibility: fits typical filter compartments and can be trimmed to size
How to use
Rinse the sponge in dechlorinated water before initial use to remove any manufacturing residues. Place the sponge in the filter compartment or designated area, ensuring it does not block water inlet or outlet passages. When used for surface cleaning, squeeze excess water and use gentle motions to wipe glass or acrylic surfaces. Replace or clean the sponge periodically: rinse in aquarium or terrarium water during maintenance to preserve beneficial bacterial colonies, and replace when the foam shows signs of permanent compression, tearing, or irreversible fouling.
Usage recommendations
For biological filtration, avoid aggressive cleaning with tap water or disinfectants that can remove nitrifying bacteria. Rinse the sponge in water removed during routine partial water changes and inspect monthly; trim to fit if necessary to maintain unobstructed flow. Store dry spares in a clean, dust-free place.
