## Long description

The Tetra FilterJet 400 is an internal aquarium filter designed for mechanical and biological filtration in home aquariums. Installed inside the tank, it delivers continuous water circulation and filtration to help maintain water clarity and reduce suspended particles. The unit is intended for routine filtration needs and is compatible with Tetra filter media, offering a compact solution for small to medium freshwater displays.
Advantages
The FilterJet 400 combines mechanical trapping of debris with biological surface area to support beneficial bacteria, helping to reduce nitrate build-up and maintain stable water quality. Its internal installation keeps equipment mostly out of view while providing adjustable flow control and straightforward maintenance access. The compact footprint makes it suitable for tanks where external plumbing or larger canister units are impractical.
Suitable for
Small to medium freshwater aquariums that require internal filtration
Community tanks with low to moderate bioload
Environments where a discreet, inside-the-tank filter is preferred
Keepers who use Tetra-compatible filter media for mechanical and biological filtration
When it may not be suitable
The FilterJet 400 is not intended for very large tanks or heavily stocked systems with high waste production; such setups typically require more powerful external canister filters or multiple filtration stages. It may also be less appropriate for aquariums that require advanced chemical filtration options or for users who need highly adjustable multi-stage filtration.
Key specifications
Type: Internal aquarium filter providing mechanical and biological filtration
Installation: Inside-tank mounting
Flow: Adjustable flow control for circulation tuning
Compatibility: Uses Tetra-compatible filter media for mechanical and biological stages
Maintenance: Removable filter cartridge and accessible housing for routine cleaning
How to use
Mount the FilterJet 400 on the inside wall of the aquarium according to the included instructions, ensuring the intake and outlet are submerged. Insert the appropriate Tetra filter media into the cartridge, connect to a power source, and adjust the flow to match the tank inhabitants' needs. Clean or replace filter media on a regular schedule to preserve flow and biological performance; rinse media gently in tank water during partial water changes to avoid disrupting beneficial bacteria.
What to consider before purchase
Tank size and bioload to ensure the filter’s capacity is adequate
Compatibility with preferred Tetra filter media and availability of replacement cartridges
Space inside the aquarium for internal mounting and access for maintenance
Desired level of flow adjustment and noise tolerance
Usage recommendations
For best results, pair the FilterJet 400 with regular partial water changes and monitoring of ammonia, nitrite, and nitrate levels. Select Tetra filter media designed for both mechanical and biological filtration and perform gentle rinses of media in aquarium water rather than tap water to preserve bacterial colonies.
