This unique little flat water filter is designed differently to an internal aquarium filter: It doesn’t hang on to anything, but rather lies horizontally in the water. It is fixed with suction cups to the bottom of the tank. Here it draws the water in from below, pumps it through the filter sponge and directs it out filtered at the top. The surface water movement makes the drinking water for reptiles visible. If you want to adjust the outflow direction, you can attach an outflow hose. Water intake from below Connection for water outlet hose Completely equipped with original EHEIM filter pad & ready to use Only 5 Watt power consumption
