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. Cal Aqua Labs' CO2 checkers allow you to monitor the CO2 level inside your aquarium. Handmade from the highest quality borosilicate glass, the CO2 checkers are an elegant addition to your planted aquarium.

Cal Aqua Labs' Nano is designed specially for small aquariums. Measuring approximately 3 cm x 3 cm, it is small enough to appear unobtrusive yet large enough to provide a clear and accurate reading.

Supplied with one suction cup.


  • Highest quality laboratory-grade borosilicate glass and artistically hand-blown
  • Fast response time
  • Supplied with 15ml Indicator Solution (4dKH). No mixing nor preparation required
  • Perfect for aquariums 1-15 gallons

Nicht nur Nano
5th June 2016

Schön kleiner Formfaktor. Auch für größere Becken geeignet, wenn man einen unauffälligen CO2-Test benötigt. Testflüssigkeit ist löblicherweise mit inbegriffen. (read more)

Der Kleinste von Allen!

Das wichtigste bei diesem Produkt: Dieser CO2-Dauertest ist wirklich _sehr_ klein! Damit wirkt er auch in Nano-Aquarien nicht zu klobig. (read more)
