Use the optional Colombo CO
2
indicator to continuously monitor
the CO
2
concentration of the aquarium water. The supply of CO
2
must be disconnected at night because plants do not absorb CO
2
when it is dark. The supply of CO
2
can be stopped automatically by
connecting the solenoid to a domestic timer.
Only use the Colombo CO
2
reactor rell for
your CO
2
reactor. The Colombo CO
2
reactor
rell contains the correct raw materials of
premium quality, ensuring the correct
results in a safe way.
Frequently asked questions:
Why is the pressure lower than 22 bar after the chemical reaction has taken place?
Maximum pressure is achieved 24 hours after the chemical reaction has taken place.
The pressure regulator is not fitted quickly enough after the water has been added.
The pressure is normal, why I don’t see bubbles in the bubble counter?
Check if the red lamp burns on the solenoid, when the lamp is on the solenoid is open.
Check if the bubble counter is filled with water
The gas is still owing after the solenoid is closed.
CO
2
gas will still be released from the diffusor, this will stop after some time.

The O-ring in the adjustment knob can be
replaced. Turn the adjustment knob
anticlockwise until it releases from the
housing to access the O-ring.
The green O-ring on the pressure regulator is
included as a spare part, when required it
can be replaced.
When the safety valve has become active or
when it is dirty, disassemble the valve and
clean it properly. Assemble the valve and see
to it that the plain of the nut and the valve
