Return Pump
The recommended flow rates for the return pumps are as shown in the
table below. The use of higher rated pumps will result in a higher water
level in the aquarium unless an appropriate modification is made to the
surface skimmer combs.

5 Operation
Initial Fill
Check that all pipes are properly assembled and that any flexible tubes
are suitably secured in position.
Install any equipment that will take up water volume in the sump before
starting to fill the system.
Open the main flow valve (rotate anti-clockwise) to maximum.
Add approximately 15cm/6” of water to the overflow box to make sure
that all the pipe joins are watertight. Check for leaks inside the cabinet.
Add water to the main tank and once it is full, monitor the water level in
the sump as it begins to fill.
As soon as there is approximately 15cm/6” of water in the main pump
compartment switch on the pump and stop adding water.
Switch on skimmers or other filters that will affect the water level in the
sump and add more water as required to maintain the 15cm/6” of water
in the main pump compartment.
Allow the system to run for a few minutes and adjust the flow valve (as
described below) so that the water level in the overflow box is at the
correct level.
Add/remove water to/from the system and adjust the flow valve until
the water levels in the system stabilise.
WARNING: Overfilling the sump with equipment or water may cause
a flood in the event of an interruption of electric power.
