A CO2 drop checker test kit is hands down the most convenient and economical way to measure the CO2 concentration in your planted tank. This little device helps you control the CO2 levels in your planted tank, which is essential for maintaining its health and success!
By looking at the colors of the indicator, you can easily see how much CO2 is in your aquarium.
🔹 Blue means there is too little CO2 concentration.
⚠️ Yellow means there is too much CO2, which is dangerous for fish!
✅ Green means there are optimum levels of CO2 for your plants and fish.
Based on your reading, you can adjust your CO2 bubble rate using your regulator, wait 2 hours for the concentration of CO2 to change, and then check your readings again.
