Make sure that the upper basket with the round grid (4) is closed and the reducing nozzle (9) is
fixed at the suction side of the pump. Furthermore, the 6-mm-connecting hose (15) has to be
attached as connection between the air space in the lid and the pump. Otherwise, the CO2-
recirculation would not work. The lid has to be put on the way that the pump outlet is situated
above the pipes of the baskets. Laterally at the lid, there is a pin that has to clutch into an
appropriate uptake of the container.
As soon as the Calciumreactor is placed in the correct position and all connections are ready, the
water flow can be started. The inlet is marked by “IN” (10), the outlet by “OUT” (12). Connection
No. 11 is provided for CO
2
. When the Calciumreactor is filled with water, CO
2
can be switched on.
The uantity of CO
2
and the flow have to be adjusted the way that the pH value in the a uarium
does not drop below pH 7.8. Within the reactor itself, the pH value should be at pH 5.9 – 6.5. The
lower the pH value in the reactor, the greater the release rate. However, the pH value is lowered
more strongly in the a uarium, dependent on the flow. It is possible to control and adjust the pH-
value in the reactor by using e. g. the A ua Medic pH Controller or A ua Medic pH-Computer.
On the top of the reactor, there is a port (24) to put in a pH-electrode. The used ph-probe has to
be pressure-resistant and it has to have a thread PG 13,5.
Before you open the Calciumreactor after filling, you have to let off the water from the lid. This is
done most simply by hanging the hose of the inlet (IN) in a lower placed bucket or into the drain.
Since the inlet is extended inside, the reactor runs dry automatically up to this point.
Please don’t pull on the cable to open the lid but reach under the lid’s edge
The back flow of the calciumbicarbonate enriched water either into the a uarium or the filter tank
should be directed to a well-flushed place in order to mix it immediately with the a uarium water.
This avoids instabilities of the pH-value. The drip counter (14), included in delivery, is used for a
safe mounting of the hose as well as for controlling the flow.
6 Maintenance
The A ua Medic Hydrocarbonate (coarse grain) is consumed by the chemical reaction and has to
be refilled from time to time. Furthermore, it should be replaced completely regularly since the
grain size decreases and thus flow and circulation drop. Also the flow rate should be checked
regularly.
The pump should be cleaned occasionally To do so, the cap of the pump housing (8) has
to be taken off One hand holds the pump inlet and the other one the pump outlet, then
the cap has to be drawn to the top Take care not to tilt since otherwise, the ceramic axle
might break
