An elegant handmade glass indicator, usable without any suction cup. Hand made with high quality glass, the CO2 Indicator can be cleaned easily using bleaching agent when dotted with algae. Indicator Solution is sold separately. Rinse glass piece thoroughly before putting it back to use.

Maintaining the appropriate CO2 level is critical in a planted aquarium. Too much CO2 may harm your fish, whereas too little CO2 decreases plant growth and allows algae to take over. The CO2 indicator makes it easy for you to know the CO2 level inside the aquarium by comparing the color of the reagent.

The CO2 Indicator can be cleaned easily using bleaching agent when dotted with algae. Rinse glass piece thoroughly before putting it back to use.


  • Transparent suction cup included
  • Made of high quality glass

Schönes Teil

Sieht optisch wirklich gut aus und macht seinen Job.

Einzig nervig ist es, das der Indicator anfangs häufig aus dem Saugnapf geflutscht ist.
