TUNZE® outlets with surface suction are an ideal solution for gravity water supply below the aquariums. An equal ratio of surface water and water from the lower water column are removed. The outlets remove only as much water as is pumped into the aquarium. On account of the light-protected construction, they are almost maintenance-free. TUNZE® outlets are supplied ready for mounting, with detailed mounting instructions. Inlet and outlet pipes are not included. Two outlet systems should be used in aquariums with more than 600 litres capacity (160 USgal.). At the outlet side, commercially available outlet pipes can be connected to the pipe sockets. However, we recommend the use of the outlet hose system 1075/2 to keep the noise as low as possible. For the inlet, we recommend our inlet hose set 1073. The connecting hose for the pump in the cabinet is included. Central Overflow (1077.000) Central overflow with surface and bottom suction up to about 1,500 l/h (400 US gal./h). Is used for aquariums with a central internal drain pipe. Fitted with a socket for PVC pipes, diam. 40 mm (1.57 in.). For complete installation, we recommend the use of screw connection, pipe and hose 1077.100.
