When starting the aquarium, water has to be filled in until the filter tank in the compartment for the
circulation pump is filled up to 15 cm and then the pump (not included) has to be started. If the water level
in the filter tank drops, fill with water until the pump no longer sucks in air. Take care that sufficient space
is left in the filter tank so that any water that flows in when the pump fails or shuts off will still fit into the
filter tank.
If the overflow produces splashing noises, the drain easy drain (Fig. 1 + 2, No. 3) should be closed in
small increments (clockwise rotation) in order to increase the water flow in the overflow. At least in the
initial phase, it has to be checked regularly and readjusted, if necessary.
Only make quarter turns and then wait at least 5 - 10 minutes so that the system has sufficient time to
compensate. Attention: the water level in the filter tank changes. If the drain is closed too much, the
water flows into the filter tank via the emergency overflow.
The divider between the skimmer and circulation pump compartment is adjustable in height and is fixed by
two screws. The optimum water level for the skimmer can be found in its manual.
To fill the storage tank (4) for refilling with water, close the tap, pull off the hose and remove the canister.
Then re-attach the hose and open the tap again. Open the tank's lid slightly so that air can flow in.
The floating gauge is adjustable in its angle, thus the water level in the pump compartment can be
adjusted. Make sure that the circulation pump does not block the floating gauge.
The filter bags (Fig. 1, No. 7) have a coarse mesh size. They can be filled with activated carbon or, to serve
as a fine filter, with usual filter cotton wool.
There is a blue fitting in the mounted bend of the return line (Fig. 2, No. 1). Here, air is sucked in when the
pump in the cabinet fails. This prevents the formation of communicating pipes and an overflow of the filter
tank by returning water.
3. Operating the aquarium
To operate the Armatus, we recommend the following products:
The circulation pump should be that strong that the total amount of water is pumped through the filter at
least 4 to 5 times per hour (for example an Aqua Medic DC Runner pump). The flow in the aquarium is done
by current pumps. We recommend Aqua Medic EcoDrift pumps, one of which is mounted on the right and
the left side of the aquarium. Mutual operation is possible with the EcoDrift Wireless Master Controller.
Important, especially when keeping stony corals, is a sufficiently sized skimmer, for example from the Aqua
Medic power flotor or K-series.
For the lighting (Aqua Medic aquarius, Qube 50 or angel LED) we recommend to take the tank volume times
0.2 W/l as the lower limit, in case of colored stony corals 0.5 to 1.0 W/l.
The Aqua Medic Tri Complex is used to supply corals with essential lime and trace elements and to
stabilize the pH-value. For pH monitoring, we recommend the Aqua Medic pH monitor. To feed the corals,
we recommend the coral food coral fit.
