The Chihiros CO2 Indicator Tiny is a compact glass drop checker designed to monitor dissolved CO₂ levels in planted aquariums. It helps aquascapers check whether the aquarium has enough CO₂ for aquatic plants while avoiding excess CO₂ that may affect fish and shrimp.
This tiny Chihiros CO₂ indicator uses CO₂ reagent liquid to show carbon dioxide level through colour change. Green indicates proper CO₂ level, yellow indicates too much CO₂, and blue indicates low CO₂. The reagent liquid is sold separately.
The Chihiros CO2 Indicator Tiny is made from high-quality glass with a clean drop-style design. It measures 32 × 35mm and includes 1 transparent suction cup, making it suitable for nano planted tanks, shrimp tanks, and compact CO₂-injected aquariums.
