Please always observe the pH-value and amend the quantity of the bubbles according to demand.
Advice: We recommend the AB Aqua Medic bubble-counter with integrated non-return valve of our
CO2 program.

Fig. 2 shows the reactor 1000 in exterior fixing together with a complete CO2 supply and
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 CO2 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
aquariums. 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 marine water, is to be at 4 – 6
minimum. It is difficult to stabilize the pH-value when it is under the 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 under 4 KH (in fresh water) the carbonate hardness is to be increased. Therefore, we
recommend the aqua+KH tablets by AB Aqua Medic.
