Filter Brush Cartridge AquaNatura TN-45188 – diameter 12 cm, length 60 cm, PP+SS

The AquaNatura Filter Brush Cartridge TN-45188 is a cylindrical mechanical filter insert designed for aquarium and pond filtration systems. With a diameter of 12 cm and a length of 60 cm, the cartridge is manufactured from polypropylene (PP) with stainless steel (SS) components. It captures suspended debris and particulate matter, helping to improve water clarity and reduce load on biological media when used as a replacement or additional stage in canister and multi-stage filters.

Advantages

The PP brush material provides a dense, open-structure surface that traps hair, plant fragments, uneaten food and other solid particles without restricting flow excessively. Stainless steel components add structural strength and resist corrosion in humid environments. The cartridge’s large length and consistent diameter make it compatible with many tubular or cylindrical filter housings and allow for prolonged service intervals compared with small, thin pads.

Suitable for

• Mechanical filtration in aquariums and garden ponds
• Canister filters and multi-stage filtration systems that accept cylindrical brush inserts
• Pre-filtration to protect biological media and pumps from clogging
• Systems requiring washable, reusable filter media to reduce consumable waste

When it may not be suitable

This cartridge is intended primarily for mechanical filtration and does not provide significant chemical filtration or biological surface area compared with specialized bio-media. It may not fit filter models that require flat pads, non-cylindrical cartridges, or very short/very narrow inserts. For water quality issues caused by dissolved organics, metals or ammonia, additional chemical or biological media will be required.

Key specifications

• Shape: cylindrical brush cartridge
• Material: polypropylene brush fibers with stainless steel components
• Diameter: 12 cm
• Length: 60 cm
• Function: mechanical particle removal / pre-filtration

How to use

Install the cartridge into a compatible filter housing according to the filter manufacturer’s instructions, ensuring correct orientation and a secure fit. Rinse the brush cartridge under running water before first use to remove any loose fibers or packaging residue. During routine maintenance, remove the cartridge and rinse thoroughly with aquarium- or pond-water (not chlorinated tap water) or dechlorinated water until visible debris is removed; gently agitate the brush to dislodge trapped particles. Replace the cartridge or its components when physical wear or persistent fouling reduces flow or cleaning no longer restores performance.

What to consider before purchase

• Confirm the cartridge diameter (12 cm) and length (60 cm) match your filter housing dimensions
• Verify that a cylindrical brush-type insert is compatible with your filter model
• Consider whether you need additional chemical or biological media for specific water quality demands
• Plan for periodic cleaning rather than frequent replacement, since the material is washable

Usage recommendations

For effective filtration, place this brush cartridge as the first mechanical stage to capture large debris, protect downstream media, and extend the service life of biological and chemical filter components. Rinse with tank or pond water during maintenance and inspect monthly for compaction or damage.
