5. Installation of circulation pumps and heater stick
The two circulation pumps are installed in the right filtration chamber.
Put each of the tubes through the designated bore holes, put the pump piece into the tubes and fix
the pumps to the back glass pane by using the rubber sucker.
The lid (Fig. 2, No. 9) of pump chamber has got a bore hole for the heater stick (not included in
shipment). If the lid is removed, i.e. for cleaning of pumps, the heater has to be switched off to
avoid a burst through overheating.
6. Installation of trickle filter pump
The aquarium water flows via two combs (Fig. 2, No. 12 and 16) and a bore hole (Fig. 2, No. 11)
with grating into the skimmer chamber. The combs can be shifted. So the relation between the
water quantity sucked on by the first comb and the quantity flowing through the bore hole located
further down in the sheet can be regulated. The higher the first of both combs is located, the lower
is the share of surface water.
The water flows from the skimmer chamber into the prefilter. The prefilter contains a removable
sponge (Fig. 2, No. 2).
The water flows further via a slide (Fig. 2, No. 21) into the trickle filter (Fig. 2, No. 4). The position
of the slide regulates the water level in the skimmer chamber.
IMPORTANT: The slide must be positioned deep enough that the water level in the
skimmer chamber is directly below the foam cup!
