Description
Dennerle Carbo Test Indicator 15ml
Dennerle Carbo Test Indicator is a precision indicator for CO2 long-term testing. Suitable for any long-term CO2 test. Includes colour matching scale for addition pH measurement.
How Dennerle Carbo Test Indicator works: The CO2 diffuses out of the aquarium water into the test container and dissolves in the indicator liquid. Depending on the CO2 content, the Dennerle Carbo Test Indicator reacts with a color change. Blue = not enough CO2 Green = CO2 level ideal Yellow = too much CO2.
