Measuring & Computer Water Tests Dennerle

Dennerle CO2 long-term tests use an indicator solution to show how the carbon-dioxide supply in an aquarium develops over time. This category includes the Carbo Test Precision, the matching Carbo Test indicator solution and the CO2 Long-Term Test Correct + pH.

A long-term test reacts with a delay and is intended for continuous observation. Position it in a suitable place according to the instructions and allow enough time for the indicator colour to stabilise. The colour and its interpretation depend on the test system and the corresponding indicator solution.

Before ordering, check whether you need a complete test unit or only a refill solution. Use only a liquid intended for the respective Dennerle test. When adjusting the CO2 supply, always observe the aquarium inhabitants as well; a long-term test does not replace cautious adjustment or monitoring of the overall aquarium conditions.
