- The easy-to-use Tzong CO2 Indicator helps you maintain an environment that is beneficial for aquarium plants
- The indicator is composed of a transparent acrylic disc that is filled with a CO2 Indicator Solution (included in the package)
- The disc is submerged into the water, while the solution inside the indicator absorbs the outgas of CO2
- The solution will change color depending on the CO2 concentration in the water - green means sufficient CO2, yellow green signifies an overdose of CO2, and blue shows insufficient CO2
- The disc's acrylic construction allows accurate reading, while the special structure design ensures that no solution seeps into the aquarium
