## Long description

Sera filter wool 500 g is loose filter media designed for aquarium filtration. The material combines mechanical debris removal with a structure that supports biological colonization, making it suitable as a prefilter or polishing layer in canister, internal and hang-on filters. Packaged loose for flexible use, the wool helps reduce visible particles and provides additional surface area for beneficial nitrifying bacteria, contributing to stable water parameters and clearer water.
Advantages
The wool provides effective mechanical filtration by trapping fine particles and detritus while its fibrous surface enables the establishment of beneficial bacteria for biological filtration. Supplied in a 500 g pack, the loose form allows easy shaping and placement to match different filter types and flow conditions. The neutral material does not alter water chemistry and can be combined with other filter media to optimise multi-stage filtration.
Suitable for
Pre-filtration in canister filters to capture large and fine particles
Polishing layer in internal or hang-on filters for improved water clarity
Temporary mechanical filtration during tank maintenance or after water changes
Support layer for biological media to increase bacterial colonisation
Key specifications
Form: loose filter wool for flexible placement
Function: mechanical trapping of particles and support for biological colonisation
Pack size: 500 g
Compatibility: can be used in canister, internal and hang-on aquarium filters
Material properties: non-reactive, neutral toward water chemistry
How to use
Rinse the filter wool briefly with aquarium water before first use to remove loose dust. Shape or layer the wool as required: use thicker layers for prefiltration to catch heavy debris and finer or thinner layers as a polishing stage to capture small particles. Place the wool in filter baskets, trays or sleeves so that water flows through the material evenly. Replace or clean the wool regularly depending on bioload and visible clogging; when used as biological support, avoid sterilising methods that would remove beneficial bacteria.
Usage recommendations
For best results, combine the filter wool with coarse mechanical media upstream and biological/chemical media downstream to maintain balanced filtration. Inspect the wool during routine maintenance and replace portions that are heavily compacted or permanently discoloured. When reusing, rinse only with aquarium water to preserve bacterial colonies.
