Quality equipment manufacturer Tunze supply a solution to a sump based system without needing a drilled tank.
"Tunze outlets with surface suction are an ideal solution for pressureless water supply below the aquariums," say Tunze.
"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."
Fitting
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.
At the outlet side, commercially available outlet pipes can be connected to the pipe sockets.
Tunze recommend the use of the outlet hose system 1075/2 to keep the noise as low as possible and hose set 1073 for the inlet.
