3. Fix the working pressure on the pressure regulator to 1 – 2 bar. The working pressure of the
regular is fixed to 1.5 bar.
4. Open the fine tuning valve of the pressure regulator slowly. When doing so, control the outgoing
CO bubbles of the bubble-counter.

5. At first, fix 15 bubbles per minute.
6. The CO gas flows into the reactor and is absorbed by the running water.

Please always observe the pH-value and amend the quantity of bubbles according to demand.
Advice: We recommend the Aqua Medic bubble-counter with integrated non-return valve of our
CO program.

Fig. 3 shows the reactor 1000 in exterior fixing together with a complete CO
controlling by Aqua Medic. The water is led into the reactor coming from the exterior filter (not
shown). The pH-Computer measures the pH-value in the aquarium and switches on the CO
supply via the solenoid valve according to demand.
This way, one can keep a constant pH-value in the aquarium (e. g. pH 6.5 – 6.8) in plant aquaria.
Nevertheless, the number of bubbles on the fine needle valve of the pressure regulator is not to be
fixed on too high values. The risk is given that the pH-value in the aquarium decreases too much
when the solenoid valve fails (e. g. blocked by dirt).
Increasing the hardness of carbonate
The carbonate hardness in aquarium water, both fresh and salt water, is to be at 4 – 6 minimum. It
is difficult to stabilize the pH-value when it is under this limit. Acids which reduce the carbonate
hardness are permanently produced by biological procedures (e. g. germ reaction). Another
carbonate hardness consumer is the filtering over peat or the setting in of other hard acids. A
weekly control of the carbonate hardness is to be executed in case of peat filtering. If the value is
