TUNZE® overflow outlets with surface and bottom suction are an ideal solution for an unpressurised water supply below aquariums. The outlets remove only as much water as is pumped into the aquarium: About 50 per cent surface and 50 per cent bottom water. On account of the opaque construction, the units are almost maintenance-free and are ready for
connection, but they are supplied without inlet and outlet pipes. Two outlet systems should be used in aquariums with more than 600 litres (158.5 USgal.).

Overflow Box 1074/2 for retrofit for up to a maximum of 1,200 l/h (317 USgal./h); requires no drillholes, and for this reason can be easily retrofitted in every aquarium. Even after an interruption of the recirculation pump, it will restart automatically. The U-shaped tube between the two chambers does not require any additional ventilation as the water velocity passes the air bubbles in the pipe into the drain chamber automatically. A minimum water flow rate of about 300 l/h (79 USgal./h) is required.. Water outlet diam. 40 mm (1.57 in.).

Overflow for supplementary installation with surface and bottom suction up to about 1,200l/h (320 USgal./h). No boreholes in the glass required, and thus it can be retro-fitted easily. Even after an interruption of the recirculation pump, it will restart the siphon automatically. With additional U pipe 1001.74 (cf. Turbelle® filter accessories), a throughput of 1,500l/h (400USgal./h) is possible. Water outlet ø40mm (1.6in.).
For easy installation and quiet operation, we recommend the use of overflow hose set 1075/2.
