Chihiros CO2 Indikator Tiny

The drop checker provides a simple visual indication of dissolved CO₂ without electricity, batteries or electronic sensors. Its clear glass construction blends into the aquarium, while the compact Tiny dimensions reduce its visual impact.

The indicator is filled with a suitable CO₂ reagent and installed underwater with its opening facing downwards. Gas exchange through the trapped air space gradually changes the colour of the solution.
