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.


  • black suction cup included
  • 5 ml Indicator solution included (has to be mixed with aquarium water). We recommend to take a precise drop checker indicator like the Aqua Rebell CO2 Check.
  • easy to read by white background

Funktioniert gut, ist preiswert, da Indikatorlösung mitgeliefert wird. Macht einen stabilen Eindruck und ist schön klein.
