## Summary description

Tetra FilterJet 900 is an internal aquarium filter by Tetra designed to provide mechanical and biological filtration for home aquariums. The unit fits inside the tank and delivers continuous water circulation and filtration to maintain water clarity and support a healthy aquatic environment. Suitable for routine aquarium maintenance and improving water quality for fish and plants.

## Long description

The Tetra FilterJet 900 is an internal aquarium filter designed for home aquariums, providing continuous mechanical and biological filtration to maintain water clarity and support aquatic life. Installed inside the tank, the unit circulates water through filter media to remove particles and promote beneficial bacteria growth, helping to stabilise water parameters and reduce maintenance frequency.
Advantages
The FilterJet 900 integrates mechanical and biological filtration in a compact internal design that fits inside most aquariums. Its water circulation improves oxygenation and distributes heat and nutrients evenly throughout the tank. The unit is intended for straightforward routine care: filter media can be accessed for cleaning or replacement, and the internal installation keeps the exterior of the aquarium clear of external hoses and attachments.
Suitable for
Small to medium home aquariums requiring internal filtration and circulation.
Freshwater tanks with community fish and live plants.
Users seeking a compact, inside-the-tank solution without external canisters or plumbing.
When it may not be suitable
The FilterJet 900 may not be sufficient for very large aquariums or heavily stocked tanks that require higher flow rates or larger media volumes. It is not a substitute for specialised filtration systems needed for advanced breeding setups, large cichlid tanks, or aquariums with heavy bioloads where external or larger-capacity filters are recommended.
Key specifications
Filter type: Internal aquarium filter with combined mechanical and biological filtration
Function: Continuous water circulation and filtration to remove particles and support beneficial bacteria
Installation: Submersible, mounted inside the aquarium
Maintenance: Access to filter media for cleaning or replacement
How to use
Mount the FilterJet 900 inside the aquarium according to the supplied mounting points and ensure it is fully submerged before connecting to power. Position the outflow to achieve desired circulation patterns without creating excessive current for the tank inhabitants. Rinse or replace filter media at regular intervals based on stock levels and water quality; avoid replacing all biological media at once to preserve beneficial bacteria. Follow the manufacturer’s safety instructions for electrical equipment near water.
What to consider before purchase
Tank size and stocking level to confirm the internal filter provides adequate flow and media capacity
Compatibility with aquarium layout and available internal space for mounting
Maintenance access for regular media cleaning or replacement
Usage recommendations
For routine maintenance, check flow and water clarity weekly and perform partial media rinses in tank water every few weeks. Combine the internal filter with regular water changes and substrate care to maintain stable water parameters for fish and plants.
