The Dennerle CO2 Long-Term Test Correct + pH enables the continuous, direct measuring of the CO2 contenct of the aquarium water. Conventional long-term CO2 tests are filled with a mixture of aquarium water and drop indicator. In contrast, the Dennerle CO2 long-term test Correct + pH employs a high-purity, ready-to-use ampoule indicator which has been developed especially by Dennerle.
This offers the following key advantages:
+ No additional measurement of carbonate hardness is necessary. Only a single colour-matching scale is required.
+ The CO2 long-term test Correct +pH indicates the CO2 content correctly at all times – independently of other acids in the aquarium water (e.g. humic acids). Measuring accuracy now also remains unaffected by any changes in carbonate hardness as a result of increases in the hardness of the water, evaporation or water changing.
+ The CO2 long-term test Correct allows direct determination of the CO2 content in millilgrams per litre – avoiding the need for additional water measurements and the laborious practice of converting values in tables. The test is equally efficient at low carbonate hardness levels.
The level of CO2 in the aquarium can be read directly from the six-colour scale in milligrams per litre. This provides an absolutely simple and reliable means of setting the correct CO2 supply level. The Dennerle CO2 long-term test Correct + pH even allows you to monitor the pH value in your aquarium at the same time! The set is sufficient for a period of 5 months.Do you have questions about this article ?
