Description
Description
The Chihiros CO2 Indicator is a glass drop checker for continuous visual monitoring of dissolved CO2 levels in planted aquariums. The indicator solution changes color based on CO2 concentration: blue indicates insufficient CO2, green indicates optimal levels, and yellow indicates excess CO2. An essential, no-electricity monitoring tool for any CO2-injected planted aquarium.
How it works
The glass vessel is filled with a pH-sensitive indicator solution and placed inside the aquarium. CO2 diffuses through the air gap inside the glass, altering the pH and color of the solution — providing a reliable, real-time visual reference without test kits.
Key features
- High-clarity glass construction
- Color guide: blue = low CO2 — green = optimal — yellow = high CO2
- No electricity or electronic sensors required
- Essential tool for CO2-injected planted aquariums
