## Summary description

Mechanical filter wool sera Biofibres coarse 400 g provides coarse-structured mechanical filtration for aquariums. Made for trapping larger particles and debris, this filter wool is used in canister and internal filters or filter boxes to reduce turbidity and protect biological media. Packaged as 400 g of coarse fibre, it is suitable for routine maintenance and media replacement.

## Long description

sera Biofibres coarse 400 g is a mechanical filter wool designed for coarse particle removal in aquariums. The product provides a coarse-structured filtration layer that intercepts larger debris, uneaten food and suspended particles before they reach biological filter media. Supplied as a 400 g package, this filter wool fits into canister filters, internal filters or filter boxes and is intended for routine maintenance and periodic replacement to maintain clear water and protect downstream filtration stages.
Advantages
The coarse fiber structure captures larger particles while allowing water to flow freely, reducing clogging of subsequent filter media. Using sera Biofibres coarse extends the life and efficiency of biological and chemical media by preventing large debris from reaching them. The material is easy to cut to size, reposition and replace during maintenance, and comes in a sufficient quantity for multiple filter changes or larger filter compartments.
Suitable for
Pre-filtration in canister filters
Internal aquarium filters and filter boxes
Routine maintenance to reduce turbidity
Protecting biological filter media from clogging
Temporary mechanical filtration during tank cleaning or water changes
Key specifications
Material structure: coarse fibers for mechanical filtration
Net weight: 400 g of filter wool
Intended use: captures larger suspended particles and debris
Compatibility: suitable for canister, internal filters and filter boxes
Form factor: compressible pad that can be cut to size
How to use
Open the package and measure the filter compartment to determine the required size. Cut the coarse wool to fit the filter tray or canister pre-filter chamber, ensuring an even layer that does not block water flow. Place the sera Biofibres coarse upstream of biological or chemical media so it traps larger particles first. Replace the wool regularly during routine maintenance or when visible clogging reduces flow; replacement frequency depends on stocking density and feeding practices.
Usage recommendations
Check the filter flow after installation to ensure the wool is not overly compacted; rinse gently with aquarium water if necessary to remove accumulated debris without harming beneficial bacteria in downstream media. For best results use coarse wool as the first mechanical stage and combine with finer mechanical or biological media according to aquarium size and bioload.
