## Summary description

ZOOLOGIA Bio round sponge, size 15×9 cm, designed for aquarium filtration and biological colonization. The porous sponge provides mechanical trapping of debris while offering surface area for beneficial bacteria to grow, supporting nitrogen cycle and water quality. Suited for freshwater and planted tanks, internal or canister pre-filter use, and routine maintenance replacement.

## Long description

ZOOLOGIA Bio round sponge 15×9 cm is a cylindrical filtration medium designed to combine mechanical debris removal with biological support for aquarium water quality. The open-cell foam traps fine particles while providing a large surface area for colonization by beneficial nitrifying bacteria. It is intended for use in freshwater and planted aquariums as a standalone internal sponge filter, a pre-filter for canister filters, or as part of routine filtration maintenance and replacement.
Advantages
The sponge delivers simultaneous mechanical and biological filtration in a single element, reducing suspended solids and supporting the nitrogen cycle. Its cylindrical shape and dimensions fit many internal filter housings and can be adapted as a pre-filter for intake pipes. The material is durable, easy to rinse and reuse during maintenance cycles, and compatible with planted tank environments due to neutral composition that does not alter water chemistry.
Suitable for
 Freshwater community and planted aquariums
 Internal sponge filters and small power filters
 Pre-filter on canister intake to protect impellers and reduce debris
 Routine filter media replacement and biological media augmentation
Key specifications
 Shape: cylindrical (round)
 Dimensions: 15 × 9 cm (height × diameter)
 Material: porous open-cell foam suitable for bacterial colonization
 Function: combined mechanical particle capture and biological surface area
 Compatibility: freshwater and planted aquarium systems, internal and canister pre-filter use
How to use
Install the sponge in the filter housing, on the intake of a canister filter, or position it as part of an internal sponge filter assembly so that water flows through the porous material. Rinse the sponge gently in aquarium water during regular maintenance to remove accumulated detritus while preserving beneficial bacterial colonies. Replace the sponge when structural breakdown occurs or when rinsing no longer restores acceptable flow and filtration performance.
Usage recommendations
For optimal biological performance, rinse the sponge in removed aquarium water rather than tap water to avoid killing beneficial bacteria. Monitor flow and water clarity after installation; use alongside mechanical pre-filters or fine floss if additional removal of very fine particulates is required. Replace on a schedule that balances bacterial retention and mechanical cleanliness—typically several months depending on bioload and maintenance frequency.
