9.3 Setting the required CO
The CO supply rate (CO bubbles/minute) required to achieve the desired pH depends on a va-
2 2
riety of factors, such as the types of plants in the aquarium, motion of the water, surface area/vo-
lume ratio, etc. The appropriate CO
the specific aquarium concerned.
• Recommendation: Begin at approx. 10 bubbles per minute per 100 l of aquarium water, i.e.
2 x 10 = 20 bubbles per minute for a 200 l aquarium.
• After 1 day, check with the pH-Controller whether the desired pH value is achieved at this ra-
te and the device is able to perform its control functions in the correct manner, i.e. whether
the connected solenoid is switched off intermittently.
• If not, the number of bubbles should be increased to approx. 15 bubbles per minute per
100 l of aquarium water. Check again after 1 day. If necessary, increase the number of
bubbles further in small steps until the desired pH is attained.
Please observe the instructions for use of the employed CO

10 Special functions

10.1 Automatic pH setting
The "Auto" function enables the ideal CO
having to refer to the table:
• Press "Auto" key: The green LED flashes, the most recently set value appears on the display
(factory setting: 04). Enter the carbonate hardness measured in the aquarium with "+"
_
and " ".
• When the keys remain unused for 3 sec., this value will be adopted. The pH-Controller calcu-
lates the exact corresponding pH value automatically and sets the system accordingly. The LED
lights up in continuous mode.
• To check the set pH value: Press "pH" key: The set value appears on the display for 3 sec.
Example: Entered carbonate hardness 6 °d
The pH-Controller sets pH 7,0 automatically (= 20 mg/l CO
• To switch off the "Auto" function: Press "pH" key and then enter the new setting with "+" and
_
" " while the green LED is flashing.
Setting range: Carbonate hardness 1 – 20 °d.
