Tetra Tetratec Internal Filter Plus, 800

The Tetra IN plus internal filter is used for mechanical, chemical and biological water treatment in aquariums and is intended for use in freshwater aquariums.

For the well-being of your fish and plants, permanent filtering of the aquarium water is necessary. Tetra filter technology safely breaks down excess nutrients and thus ensures permanently good water quality. The filter is the heart of every aquarium and is therefore chosen to fit every biotope. It is not only the size of the basin that is important, but also its inhabitants. At Tetra, all AquaArt complete sets contain the right filter for the fish stock suitable for the respective aquarium. However, if the circumstances change because the fish are multiplying or very small animals such as dwarf shrimp are feeding in, the existing filter may also have to be replaced by a more suitable one. Here Tetra offers a variety of devices that are suitable for all tank residents and aquarium sizes.

The Tetra IN plus internal filter can do more than just mechanical and biological filtering: it also creates a natural flow in the aquarium and enriches the water with oxygen, and all in one step! It can be easily adjusted to the needs of your aquarium. Neither hoses nor a base cabinet are required for installation. The filter is placed directly in the aquarium. The closed filter chamber ensures that the dirt does not get into the aquarium water - even when cleaning! Due to its black, compact design with the black filter sponges, it fits inconspicuously in the aquarium. The surface structure of the filter sponges offers bacteria an ideal area to colonise.
The filter chambers are divided into two, so that a filter sponge always remains in the filter chamber during cleaning, which minimises the loss of useful bacteria. When cleaning, the device remains in the aquarium - thanks to the practical filter medium removal device, handling is clean and child's play. The flow rate can be regulated continuously and adapted to the aquarium. The outlet nozzle can be rotated 180 °, the adjustable Venturi system enables an additional oxygen supply. Thanks to the stable suction cups, the internal filter is easy to use. The filter media are available as spare parts. The Tetra IN plus internal filter is TÜV / GS tested, CE certified and has a 2 year guarantee.

Tip: Filter cleaning and changing always mean a loss of filter bacteria. With Tetra Bactozym, the bacterial activator, you can compensate for this loss in no time.

With the Tetra IN plus internal filter you not only guarantee the optimal treatment of your aquarium water, but you also regulate the oxygen content and can clean it without having to lift it completely out of the water!
