Product information

Description

Tetra IN plus IN 300 is an internal aquarium filter designed for use inside freshwater home aquariums. The unit provides combined mechanical and biological filtration with replaceable media to help maintain clear water and stable water parameters. Its compact internal mounting reduces external equipment clutter while ensuring continuous water circulation and oxygenation for fish and plants.

Advantages

The filter integrates mechanical and biological filtration stages in a single compact housing, enabling removal of particulate matter and supporting beneficial bacterial colonization. Its replaceable media simplify maintenance and allow targeted cleaning or media exchange. Installation inside the tank offers a neat appearance and quieter operation compared with some external systems. The design supports continuous water circulation, which helps reduce dead zones and improves gas exchange at the water surface.

Suitable for

  • Small to medium freshwater aquariums requiring internal filtration
  • Home tanks where compact, unobtrusive equipment is preferred
  • Setups needing mechanical removal of debris and biological filtration to support stable water chemistry

Key specifications

  • Type: Internal aquarium filter with mechanical and biological filtration
  • Mounting: Inside aquarium, compact profile for minimal visual impact
  • Media: Replaceable filter media for mechanical and biological stages
  • Flow: Continuous water circulation suitable for maintaining oxygenation and reducing stagnant zones
  • Suitable water type: Freshwater aquariums

How to use

Install the filter inside the aquarium following the manufacturer’s mounting guidelines so the unit is submerged to the recommended level. Fit the supplied or compatible replaceable media into the filter cartridge and connect to power using a protected outlet. Allow the filter to run continuously to establish biological filtration; initial cloudy water is common as beneficial bacteria colonize the media. Maintain water level and avoid running the filter dry.

Usage recommendations

Perform regular maintenance by rinsing or replacing mechanical media when visibly clogged and replacing biological media according to the manufacturer’s schedule to avoid loss of beneficial bacteria. Monitor flow and water clarity, and combine the filter with routine partial water changes and debris removal for best results.
