The TetraAH 50-400 Air Pump Hose is a transparent silicone hose for use with the Tetra APS 50-400 Aquarium Air Pumps and most other air pumps and vents.

To operate air-operated sponge filters or to increase the oxygen content by increased surface movement, an aquarium air pump is essential. The Tetra APS aquarium air pump 50 is a very quiet and extremely powerful air pump, which has a runs very smoothly thanks to sound-absorbing chambers. Thanks to the innovative pump construction with strong housing walls and special, vibration-absorbing rubber feet, very quiet operation is possible. The Tetra APS air pump impresses with exceptional quality and reliability and provides constant high air flow through a durable and powerful membrane. An air valve to control the air flow is enclosed with the packaging. The operation is very easy. The Tetra APS aquarium air pump 50 is TÜV / GS tested, as well as CE certified and has a 3-year warranty.

The Tetra AH 50-400 air pump hose is connected between the air pump and the sponge lift filter or the aeration stone in the aquarium. The length of the hose can be shortened by cutting.

Note: Outflow stones may clog after a while. Then there is an increased back pressure, which reduces the performance of the air pump and leads to increased wear of the membrane. Therefore, replace your air stone at regular intervals as soon as you notice a reduced air outlet, or if the air stone is visibly dirty or calcified.
