Dennerle CO2 long-term test correct + pH

Dennerle CO2-langetermijntest correct + pH

The colouring of the special CO₂ indicator varies according to the CO₂ content from

• blue = not enough CO₂ to
• green = CO₂ content ideal and
• yellow = too much CO₂.

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.

Special CO2 indicator for particularly simple and accurate CO2 control

Conventional long-term CO2 tests are filled with a mixture of aquarium water and indicator. This involves various disadvantages, one being that the acids which are present in all aquarium waters (e.g. humic acids, nitrate, etc.) can lead to incorrect test results. The DENNERLE CO2 long-term test Correct employs a ready-to-use special CO2 indicator which is used on its own, rather than in a mixture with aquarium water.

In addition to the CO2 concentration, the pH value can also be displayed on a 6-colour scale. Here this depends on the carbonate hardness. For each carbonate hardness measured, there is a corresponding 6-colour scale provided in the package. Here the pH value can now be read easily using the colour of the CO2 special indicator.
