## Long description

ZOOLOGIA round sponge 15/9 is an aquarium filter sponge designed for mechanical filtration and debris retention. The cylindrical sponge with dimensions 15 mm by 9 mm fits compatible filter housings and provides a porous surface to trap particles, uneaten food and detritus while allowing water to pass through. The material supports colonization by beneficial bacteria, helping to maintain biological balance in both freshwater and marine systems. The product is intended for routine maintenance, media replacement and targeted cleaning of small powerheads or cartridge-style filters.
Advantages
The sponge delivers consistent mechanical filtration with fine porosity to capture suspended solids without significantly restricting water flow. Its compact round shape and standardized dimensions make installation and replacement straightforward in compatible filter units. Made from resilient foam, the sponge holds its shape through repeated rinsing and is suitable for gradual bacterial colonization, contributing to stable aquarium conditions. The neutral color and simple design are unobtrusive inside filtration compartments.
Suitable for
 Small internal and external filter cartridges that accept 15 mm × 9 mm round inserts
 Powerheads, sponge filters and circulation devices requiring compact mechanical media
 Freshwater aquariums, planted tanks and marine nano-setups for particulate removal
 Routine filter maintenance and partial media replacement
Key specifications
 Shape: round/cylindrical
 Dimensions: 15 mm (outer diameter) × 9 mm (thickness/height)
 Material: open-cell foam for mechanical filtration and bacterial colonization
 Function: mechanical filtration and debris retention
 Compatibility: designed for filter housings and cartridges matching the 15/9 size
 Usage environment: suitable for freshwater and marine aquaria
How to use
Rinse the sponge gently in dechlorinated or tank water before first use to remove any loose particles. Insert the sponge into the filter compartment or cartridge slot that matches the 15 mm × 9 mm size, ensuring a snug fit without compressing the foam excessively. During routine maintenance, remove the sponge and rinse it in aquarium water to preserve beneficial bacteria; avoid using tap water with chlorine or strong detergents. Replace the sponge when it becomes torn, permanently deformed or when rinsing no longer restores adequate flow and clarity.
Usage recommendations
 For optimal results, combine the ZOOLOGIA round sponge 15/9 with biological media in the same filter to maintain mechanical and biological filtration balance. Inspect the sponge during regular water changes and replace on a schedule matched to stocking density and feeding rates to preserve water clarity and system stability.
