Connect the bottom end of the tube to the air intake of the pump.
The water inlet is located at the opposite side of the outlet pipes. Attach the union and the hose tail (22 x 20
mm).
We recommend a pump with a capacity of 2,000 to 4,000 litres/hour (500 – 1,000 gph) e. g. Aqua Medic Eco
Runner 3700 for the water supply.
Take care that the ball valve at the bottom is closed before you start to fill the skimmer! Ensure the availability
of a sufficient quantity of usable saltwater.
The single 6.0 takes approx. 50 litres of water, the type 5000 baby ECO approx. 25 litres.
● Fit the rubber sealing ring for the bayonet socket of the reaction pipe. Push the bayonet socket into its seating
and turn it to the right as far as possible. Then fit the collection cup.
The drain from the skimmer has to run freely into the aquarium. A PVC pipe (40 mm dia) can be glued into the
drain ports. It is possible to let both drains flow into one pipe but the diameter of the pipe must not be reduced.
If the drains are left separate, a reduction in pipe size to 32 mm is possible.
The skimmer can now be filled by pumping directly from the aquarium.
Ensure, that the water level of the aquarium is not lowered too much.
-
As soon as the water level in the skimmer reaches the height of the venturi pumps, these pumps should be
-
started.
Top up with sea water as necessary.
-
After first use or after cleaning the skimmer, it takes some time for the initial foam to build up in the reaction
pipe of the collection cup. This is because the cleaned acrylic initially reacts with the water until a build up of
fatty acids naturally takes place.
After approx. 24 hours, the foam should be pushed slowly and evenly into the collection cup. The quantity of
liquid and organic substances depends on the pollution of the aquarium.
5. Maintenance
Foam cup:
Depending on the organic load the cup should be cleaned daily to weekly.
Skimmer pipe: This needs only occasional cleaning, we recommend intervals from 6 to 12 months.
Venturi pump:
The maintenance of the pump should be done at the same time as that of the
reaction pipe.
Drain the water out and dismantle the pump. Flush the pump housing and power wheel with clean water. The
same should be done with the air injection nozzle. Important: The air duct in the ceramic axle and the
boreholes in the impeller plate have to be clear. Otherwise, the pump might be overheated that could lead to
total failure.
6. Failures
Failures may arise if:
The ratio between supplied air and the water volume is not correct.
-
Cause:
The air injection nozzle is clogged or the pump chamber containing the air wheel is dirty.
Action:
Dismantle the venturi pump, clean it thoroughly, carefully clean the air injection nozzle with a thin brush or
blunt instrument and re-assemble the pump again.
The venturi pump does not re-start after an interruption of the power supply.
-
Cause:
The water pressure is too high.
