CO2 Drop Checkers are used for long-term monitoring of the CO2 levels in the aquarium. A CO2 reagent is filled into those CO2 Drop Checkers and will change the color according to the amount of dissolved CO2 in the aquarium water. Green will indicate a proper CO2 value, yellow will indicate to much CO2 and blue will show not enough CO2.

The indicator solution turns green at approx. 20-25 mg/l of CO2.


  • White suction cup included
  • Easy to read by white background
  • With indicator solution

Bedingt empfehlenswert
26th October 2018

Das Teil an sich ist sehr gut. Die mitgelieferte Messflüssigkeit zeigt nur blau an egal wieviel CO2 ich dosiere darum nur bedingt empfehlenswert.
