Tetra IN 400 Plus Internal Filter

Tetra Internal IN 400 Plus Filter

The powerful and ultra-professional 400 Plus Internal Filter from Tetra combines high quality physical. chemical and biological filtration with a number of sensational benefits to provide all-round efficiency within a compact and elegant design. The filter has been developed for ideal suitability in aquaria up to 60 litres.

The Tetra Internal IN 400 Plus filter uses key features such as a practical filter medium removal device to ensure clean use, together with an innovative outlet nozzle which can be rotated 180° and an improved controllable venturi system which provides an additional oxygen supply (by blowing bubbles into the water without any loss of flow rate or filter performance).

The Tetra Internal IN 400 Plus filter also brings additional benefits to water clarity such as its two filter chambers for maximum efficiency and continuous control of the flow rate throughout the tank for ideal regulation. The device offers an advantage in that it remains within the tank throughout the entire cleaning process whilst the impeller can be easily removed. Two sponges allow for one filter foam to always remain in the filter chamber during the cleaning process to reduce the loss of beneficial bacteria.

Via its small and incredibly discreet size, the 400 Plus internal filter is easy to attach courtesy of its stable adhesive stickers which mount effortlessly to the sides of the tank taking up minimal space, making it an ideal option for fuller and more compact aquarium sizes.

The split chamber feature allows for the option of a combined biological / mechanical foam (TetraTec BF sponge) in one (for removing ammonia and solid waste) and an optional carbon foam (TetraTec CF sponge) for maintaining crystal clear water results.
