## Long description

Sera Filter Wool fine-grain is a mechanical filter media supplied in a 1 kg pack for aquarium filtration. The product is intended to capture fine particulate matter and debris in the mechanical stage of filtration and can be used in internal and external filters, sumps, and custom or DIY filter assemblies. It can serve as primary mechanical filtration or as a polishing layer to improve water clarity and reduce suspended solids.
Advantages
Fine-grain structure provides a large surface area that traps small particles without significantly restricting water flow when installed correctly. The material is flexible and can be cut or shaped to fit different filter compartments and sizes. Being a mechanical-only media, it does not affect water chemistry and is compatible with biological and chemical filter stages when placed upstream as a pre-filter or downstream as a polishing layer.
Suitable for
 Internal hang-on and canister filters as a mechanical stage
 Sumps and DIY aquarium filter boxes
 Polishing layer to remove fine suspended particles before biological or chemical media
 Temporary use during tank maintenance or after substrate disturbance to clear cloudiness
When it may not be suitable
This filter wool is intended strictly for mechanical filtration and will not remove dissolved organics, nutrients, or chemical contaminants; it should not be relied upon as the sole method for controlling water chemistry. In systems with extremely high particulate load, the fine fibers may clog quickly and require frequent replacement or cleaning. It is not a replacement for biological media when establishing or maintaining biological filtration.
Key specifications
 Form: fine-grain filter wool
 Pack size: 1 kg
 Intended function: mechanical removal of suspended solids and debris
 Compatible placement: internal filters, external filters, sumps, DIY filter housings
 Material behavior: cuttable and shapeable for custom fit
How to use
Remove the required amount of filter wool from the pack and cut or shape it to fit the filter compartment. Place the wool where water first enters the mechanical stage for maximum particle removal, or use a thin layer at the end of the filter path as a polishing stage to improve clarity. Monitor flow rate and replace or rinse the wool when it becomes visibly clogged or when flow is reduced. For rinsing, use aquarium water during water changes to avoid introducing contaminants; replace the media when rinsing no longer restores adequate flow.
What to consider before purchase
 Only provides mechanical filtration; additional media needed for chemical or biological filtration
 Replacement frequency depends on stocking, feeding, and particulate load
 Ensure you have space in your filter for a 1 kg supply or plan on cutting to size
 Not suitable for directly treating dissolved substances or for long-term biological colonization
Usage recommendations
For routine use, place the fine-grain sera filter wool upstream of biological media to protect later stages and prolong their service life. Check mechanical stages weekly in heavily stocked tanks and replace or clean the wool as needed to maintain flow and water clarity.
