## Long description

Tetra IN plus IN 600 is an internal aquarium filter engineered for freshwater tanks with a capacity of 50–100 L. The compact device combines mechanical and biological filtration in a single unit that sits inside the aquarium, providing continuous water circulation and helping to maintain water clarity and a stable environment for fish and plants. Designed for hobby aquarists, the filter supports routine water maintenance and reduces particulate matter and organic load without taking up exterior space.
Advantages
The Tetra IN plus IN 600 offers integrated mechanical and biological filtration in a compact internal design that is easy to position inside the tank. Its silent operation and steady flow help create uniform circulation throughout the aquarium while the replaceable filter media enable effective removal of debris and support beneficial bacterial colonization. Installation and routine maintenance require minimal tools and can be completed without draining the aquarium.

 Freshwater aquariums with volumes between 50 and 100 litres

How to use
Mount the Tetra IN plus IN 600 inside the aquarium following the supplied instructions, ensuring the unit is fully submerged and securely fixed to a smooth surface. Connect to a suitable power outlet with the power switched off, then adjust the flow control to achieve the desired circulation level for your tank inhabitants. Replace or clean the mechanical filter media regularly to prevent clogging and maintain flow; maintain biological media by gentle rinsing in tank water during partial water changes to preserve beneficial bacteria. Monitor water parameters and flow performance as part of routine aquarium care.
Usage recommendations
Position the filter where it will promote even water movement across the tank and avoid directing flow directly at delicate plants or small, weak-swimming species. Schedule regular inspections of the outlet and impeller to prevent blockages from debris. When performing maintenance, use aquarium water to rinse biological media to retain microbial populations. Follow manufacturer guidance for replacement intervals of consumable filter inserts to sustain filtration efficiency.
