## Long description

Tetra FilterJet 900 is an internal aquarium filter designed for mechanical and biological filtration inside freshwater and community aquariums. Installed inside the tank, the FilterJet 900 circulates water through its filter media to remove suspended particles, reduce turbidity and create conditions for beneficial bacteria to colonize. The unit is intended for small to medium home aquaria where compact, in-tank filtration and gentle water movement are required.
Advantages
The compact design of the Tetra FilterJet 900 allows discreet installation inside the aquarium without taking up external space. It combines mechanical and biological filtration in a single unit to capture debris and support nitrifying bacteria. Adjustable flow and easy access to the filter compartment simplify routine maintenance. The internal placement reduces plumbing complexity and is suitable for aquarists who prefer a simple, self-contained filtration solution.
Suitable for
 Small to medium freshwater aquariums
 Community tanks with non-aggressive fish species
 Environments where in-tank, compact filtration is preferred
 Tanks requiring moderate water circulation and basic biological filtration
Key specifications
 Filter type: Internal aquarium filter providing mechanical and biological filtration
 Intended water: Freshwater aquaria
 Placement: Submerged, inside the aquarium
 Flow control: Adjustable flow rate (user-adjustable output)
 Filter media: Integrated mechanical media with space for biological media
 Maintenance access: Front or top-access filter compartment for media replacement and cleaning
 Power: Low-voltage electric operation suitable for continuous use
How to use
Mount the Tetra FilterJet 900 inside the aquarium following the manufacturer's mounting instructions, ensuring the unit is fully submerged and positioned to provide effective circulation throughout the tank. Fill the filter compartment with the recommended mechanical and/or biological media, then connect the power supply and set the flow to the required level for your aquarium size and stocking. Monitor water flow and clarity during the initial run-in period; allow time for beneficial bacteria to establish on the media before relying on biological filtration alone.
Usage recommendations
Perform regular maintenance by rinsing or replacing the mechanical media when visibly clogged and by periodically checking biological media without using chlorinated tap water. Adjust the flow to avoid strong currents for species that prefer calmer water. Use the FilterJet 900 as part of an overall aquarium maintenance routine that includes regular water changes, substrate cleaning and monitoring of water parameters.
