## Summary description

Tetra IN 600 plus is an internal aquarium filter designed for tanks with capacity from 50 to 100 L. It provides internal mechanical and biological filtration, with compact installation inside the aquarium to circulate and clarify water. Suitable for small community and planted aquaria, it helps maintain water quality, reduce debris and support stable biological conditions.

## Long description

Tetra IN 600 plus is an internal aquarium filter intended for aquaria with a volume of approximately 50–100 L. The compact unit installs inside the tank and integrates mechanical and biological filtration to circulate and clarify water. Designed for use in small community and planted tanks, the filter supports removal of suspended particles, promotes beneficial bacterial colonisation and contributes to more stable water parameters.
Advantages
The internal design keeps equipment inside the aquarium, saving external space and simplifying installation. Mechanical filtration captures visible debris while the biological stage provides a surface for nitrifying bacteria to reduce ammonia and nitrite. The unit operates with low noise and steady flow to minimise disturbance to fish and plants. Compact dimensions and straightforward maintenance make it suitable for routine aquarium care.
Suitable for
Community freshwater aquaria with volumes from 50 to 100 litres
Planted tanks that require gentle water flow and biological support
Small species and community fish where internal mounting is preferred
Environments needing regular removal of suspended particles and debris
Key specifications
Recommended aquarium volume: 50–100 L
Filtration types: mechanical and biological
Internal installation suitable for submersion inside the aquarium
Compact size for unobtrusive placement within the tank
Designed for continuous operation with low noise
How to use
Install the filter inside the aquarium at a location with good water circulation, following the manufacturer’s mounting instructions for secure placement. Prime the unit and connect to power using a safe, dry outlet in accordance with electrical safety practices for aquaria. Replace or clean mechanical media regularly to preserve flow rate and prevent clogging; leave biological media intact when cleaning to conserve beneficial bacteria. Monitor water flow and condition during initial operation and after routine maintenance.
Usage recommendations
For optimal performance, perform regular partial water changes and maintain the filter media according to the level of stocking and feeding. Avoid cleaning all biological media at once; rinse it gently in aquarium water to preserve bacterial colonies. Position the outlet to create gentle circulation without disturbing plants or sensitive species.
