## Long description

AquaNatura TN-45189 filter media discs are compact polypropylene inserts designed for aquarium filtration. Each disc has a diameter of 10 mm and a height of 7 mm, making them suitable for tight filter housings, sponge chambers and custom assemblies in freshwater aquariums. These PP discs act as mechanical trap elements for suspended debris and provide surface area for biofilm development to support biological filtration and improve overall water clarity.
Advantages
Made from durable polypropylene, these filter media discs resist breakdown and retain shape under typical aquarium flow conditions. Their small, uniform size allows even packing and consistent flow through sponge chambers and cartridge compartments. The smooth yet slightly textured surface encourages colonization by nitrifying bacteria while remaining easy to rinse and maintain. The neutral material does not alter water chemistry in freshwater environments.
Suitable for
Compact internal and external aquarium filters
Sponge filter chambers and DIY filtration units
Mechanical pre-filtration to capture debris and waste
Biological filtration support for freshwater tanks
Key specifications
Material: polypropylene (PP)
Diameter: 10 mm
Height: 7 mm
Form: solid disc-shaped media
Intended use: mechanical and biological aquarium filtration in freshwater systems
How to use
Place the AquaNatura PP discs into a filter chamber, sponge compartment or mesh bag so that water flows evenly through the packed media. For mechanical filtration, position the discs upstream of finer media to trap larger particles first. For biological support, allow the discs to remain in place so a stable biofilm can develop; avoid aggressive cleaning that would remove beneficial bacteria. Rinse gently in aquarium water when performing maintenance to remove accumulated debris while preserving bacterial colonies.
Usage recommendations
Choose a packing density that allows water to pass through without creating excessive flow resistance; check filter flow after installation. Replace or deep-clean discs only as needed—regular gentle rinsing is usually sufficient. Use these PP discs in freshwater setups; verify compatibility before using in planted tanks with specialized CO2 or chemical dosing regimes.
