Product Information

As a well-known manufacturer, Tetra can be relied upon to create a powerful, yet efficient internal filter. Their range of In Plus Internal Filters offers a great performance and convenient features too. Compact enough to leave space for fish and plants, the filters still offer the best results.

The waste and pollutants found in a tank are created by the life within, so this is generally a build-up of ammonia and other waste. If not removed if not only looks unsightly, but can also harm fish and plants. The In Plus collection uses biological, chemical and mechanical filtration to fully eradicate this waste from the water.

The unit holds two media sponges in separate chambers. One can be left in whilst the other is cleaned, so as not to disturb the helpful bacteria that has developed.

Ensuring that the oxygen within the water is disseminated successfully will increase the health of your tank and make sure there are no stagnant spots. The Tetra range of filters has a 180⁰ rotating water outlet to provide movement to the clean water leaving the filter. Plus, it has a Venturi section, which allows air into the filter.

Available in various formats to suit tanks from 40 to 200 litres in size, the Tetra range is perfect for any aquarium.
