2
packing with minicascades

Principle of Operation
The method employed for fertilizing aquarium plants with
CO is based on that the fact that CO
2
under certain conditions. Dissolved CO
the water in the aquarium and is picked up by the plants.
The pressure relationships, water flow rate, and dwell time
of water in the CO -Reaktor S's housing are regulated
2
such that CO is able to diffuse into aquarium water at a
2
high rate.
Preparing the Dupla CO -Reaktor S for Use
2
The Dupla CO -Reaktor S's high capacity promotes rapid
2
diffusion of large volumes of CO
which is why we recommend that the Dupla CO
tor S be installed on a separate pump circuit. The
important things here are that the Dupla CO
inlet be connected to the pump's outlet and that the entire
circuit be free of leaks. Before installing and operating
the unit, you should thus verify that the O-ring seals on the
screw-on caps sealing the regulator fittings on the
reactor's housing are correctly seated and that the caps
have been securely tightened.
Installing and Operating the Dupla CO
Inside an Aquarium
1. Connect the pump's outlet to the fitting on the water
inlet on the Dupla CO -Reaktor S's housing using a
2
length of 9-mm i.d. flexible tubing.
2. Clamp the tubing onto the fitting using the threaded
collar (cf. Figure 1).
3. Connect the low-pressure outlet (max. pressure
1.5 bar) on your CO -supply system to the fitting on
2
the CO -inlet on the Dupla CO
2
using a length of 3-mm i.d. flexible tubing (cf.
Figure 2).
4. Attach the Dupla CO -Reaktor S to the inner wall of
2
your aquarium using the pair of Duplakon suction
cups provided.
5. The Dupla CO -Reaktor S is now ready for use.

6. Switch on the pump.
7. Gradually open the regulator valve on the CO
line. Note: We recommend inserting a
Dupla CO -bubble counter into the supply line in

Installing and Operating the Dupla CO
Outside an Aquarium
1. Mount the wall bracket at the location provided in the
cabinet beneath your aquarium.
2. Connect the Pump's outlet to the fitting on the water
inlet on the Dupla CO -Reaktor S's housing using a
2
length of 9-mm i.d. flexible tubing.
3. Clamp the tubing onto the fitting using the threaded
collar (cf. Figure 1).
4. Connect the low-pressure (max. pressure 1.5 bar)
outlet on your CO -supply system to the fitting on the
2
CO -inlet on the Dupla CO
2
a length of 3-mm i.d. flexible tubing (cf. Figure 2).
5. Push one end of a length of 9-mm i.d. flexible tubing
onto the fitting on the water outlet on the
Dupla CO -Reaktor S's housing and insert its other
2
end into the aquarium (cf. Figure 3).
6. Clamp the tubing onto the fitting using the threaded
collar.
7. Clamp the Dupla CO -Reaktor S onto the wall bracket.
2
8. The Dupla CO -Reaktor S is now ready for use.
2
9. Switch on the pump.
10. If there should be any air present in the system,
remove the Dupla CO -Reaktor S from the wall
2
bracket, rotate it through 180°, hold it in this position
until all of the air has been expelled from the system,
and then clamp it back onto the wall bracket.
11. Gradually open the regulator valve on the CO
line. Note: We recommend inserting a
Dupla CO -bubble counter into the supply line in
2
order to allow monitoring CO
Selecting CO -Diffusion Rate
2
The CO -diffusion rate is user selectable, and is selected
2
by puncturing the diaphragm of one of the regulator
fittings using the pin provided (cf. Figure 4). The resultant
CO -diffusion rate increases from the top regulator fitting,
2
which yields the lowest rate, to the bottom regulator fitting,
which yields the highest rate. If the Dupla CO
is to be operated outside the aquarium, you will have to
connect the regulator fitting whose diaphragm has been
punctured to the aquarium using a length of 3-mm i.d.,
flexible tubing. Any unused regulator fittings with
punctured diaphragms should be sealed using the screw-
on caps provided (cf. Figure 5).
