## Long description

AquaNatura filter brush cartridge TN-45185 is a cylindrical replacement filtration insert designed for mechanical removal of suspended particles in aquarium filtration systems. Constructed from polypropylene (PP) bristles and stainless steel (SS) core elements, the cartridge measures 12 cm in diameter and 30 cm in length. Its brush-style structure captures detritus, uneaten food and plant debris while maintaining water flow, supporting clearer water in both freshwater and marine aquaria.
Advantages
The PP bristles provide durable mechanical filtration that resists breakdown in continuous wet conditions, while the stainless steel components ensure structural stability and secure attachment inside compatible filter housings. The cylindrical form offers a large surface area for particle capture without significantly restricting flow, and the washable material allows repeated use after rinsing. The cartridge’s standard dimensions make it suitable for many canister and internal filter systems that accept brush-style inserts.
Suitable for
 Mechanical filtration in freshwater aquariums
 Mechanical filtration in marine and reef tanks
 Replacement of worn or clogged brush-style filter inserts
 Pre-filtration before biological or chemical media
Key specifications
 Shape: Cylindrical brush cartridge
 Diameter: 12 cm
 Length: 30 cm
 Outer material: Polypropylene (PP) bristles
 Core/structural elements: Stainless steel (SS)
 Function: Mechanical particle capture and debris retention
How to use
Install the cartridge into a compatible filter housing or holder so that water flows through the bristle surface. For canister filters, place the brush cartridge in the mechanical filtration stage ahead of biological and chemical media. Rinse the cartridge periodically in tank water during maintenance to remove trapped particles; avoid using hot water or detergents. Inspect the stainless steel components for corrosion and ensure the cartridge remains securely seated to maintain proper flow and filtration efficiency.
Usage recommendations
For routine maintenance, rinse the brush cartridge every 2–4 weeks depending on bioload and visibility of trapped debris. Replace the cartridge if bristles become excessively worn or the stainless steel core shows signs of corrosion. Use as pre-filtration to prolong the life of biological and chemical media and to maintain water clarity.
