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

Perfect for nano tanks!
4th September 2019

This is the smallest drop checker I could find for my 45f tank. It really is tiny but does what it is supposed to do, while taking as little space as possible in the tank. (read more)
