## Long description

Internal aquarium filter Kinvara Aqua Natura TN-44801 is an in-tank filtration unit with an ABS housing measuring 90×85×300 mm. The filter contains a layered set of media: a polyester sponge for mechanical filtration, activated carbon for chemical adsorption, and ceramic rings for biological filtration. It is designed for freshwater and planted aquariums to improve water clarity, reduce odors and support colonization of beneficial bacteria while maintaining circulation.
Advantages
The filter combines three filtration stages in a compact ABS body, providing mechanical, chemical and biological treatment of aquarium water. The polyester sponge captures debris and particulate matter, activated carbon reduces dissolved organics and odors, and ceramic rings supply a porous surface for nitrifying bacteria. Its vertical, slim design fits inside tanks without occupying excessive space and is suitable for continuous operation with low maintenance requirements.
Suitable for
 Small to medium freshwater aquariums
 Planted tanks requiring gentle circulation and clear water
 Extended biological filtration for community fish setups
 Aquaria where odor reduction and removal of dissolved compounds are needed
Key specifications
 Housing material: ABS plastic
 Filtration media: polyester sponge, activated carbon, ceramic rings
 Unit dimensions: 90 × 85 × 300 mm
 Filtration stages: mechanical, chemical, biological
 Orientation: internal/in-tank installation
How to use
Install the filter inside the aquarium so it stands vertically and is fully submerged, following manufacturer safety instructions for electrical connections. Rinse the polyester sponge and ceramic rings with dechlorinated water before first use; do not rinse activated carbon if pre-packed for immediate use. Place the layered media in the filter chamber in the order recommended by the manufacturer so water passes through sponge, carbon and ceramic. Prime the filter and ensure gentle flow appropriate for the tank’s inhabitants; monitor water clarity and flow during initial operation.
Usage recommendations
Perform regular maintenance by rinsing the polyester sponge in aquarium water during water changes to preserve mechanical filtration efficiency. Replace activated carbon according to water quality needs, typically every 3–6 weeks, and inspect ceramic rings for excessive clogging; clean them gently in tank water to retain beneficial bacteria. Adjust flow and positioning to avoid strong currents that may disturb plants or delicate fish.
