6.4 Replacing the CO special indicator
In order to ensure the fastest and most accurate colour reaction, we recommend filling the test container every 4-6 weeks with
fresh CO special indicator fluid. You can pour used indicator fluid down the drain in your home.
6.5 Cleaning the CO long-term test
Use warm water and soft sponge. Do not use cleaning agents.
6.6 Special information
• The CO special indicator is safe and free of chemical solvents. Nevertheless avoid prolonged skin and eye contact.
• Indicator liquid that accidentally enters the aquarium is harmless for all aquarium inhabitants.
• Store indicator liquid away from sunlight, heat and frost. Always store ampoules in a place that is not exposed to direct
light. Filling level due to technical reasons.
6.7 If you want to know more: How to determine the CO content in the aquarium
CO concentration, carbonate hardness (KH) and pH are in a certain ratio to one another. The CO concentration of the water
can be calculated from the pH and carbonate hardness. Suitable pH and KH tests can be obtained from specialist retailers.
• Measure the carbonate hardness of the aquarium water.
• In the table, read the corresponding pH value for the desired CO concentration. You should adjust the pH +/- 0.1 by
appropriately regulating the bubble count.
Example: Carbonate hardness 4 °d, desired CO content 20 mg/l = recommended pH 6.8

7.1 Replacing disposable CO bottle
• The pressure reducer can be unscrewed at any time – the bottle valve closes automatically.
• Screw the pressure reducer onto a new CO disposable bottle (see 4.1).
