Achieve healthier, more vibrant aquatic plants with this easy-to-use Aquarium CO₂ Indicator Test Kit. Designed to provide continuous, accurate monitoring of your tank’s carbon dioxide levels, this kit helps you maintain the perfect balance for optimal plant growth and a stable, thriving ecosystem.
The kit includes a high-visibility drop checker and a specialized CO₂ indicator solution that reacts in real time. As CO₂ levels change, the solution shifts color—making it simple to see whether your tank has too little, too much, or just the right amount of CO₂. No guesswork, no complicated testing.
Ideal for planted tanks of all sizes, this kit helps prevent issues like algae outbreaks, poor plant health, and stressed fish by ensuring CO₂ levels remain within the ideal range.
Test solution results
Blue : low concentration will lead to slow growth and maybe even plant die off
Green: co2 concentration is in the correct range which will lead to stable and pristine plant health and growth rates
Yellow: co2 concentration is too high can cause fish and shrimp to die due to hypoxia and plants will struggle to photosynthesize.
includes either 1 bottle and indicator solution or 1 set and indicator solution
