Don’t know how to measure the CO2 in your planted tank? Try this CO2 tester or “drop checker”.
You just need to add drop checker indicator mix to the CO2 drop checker and wait. After a few hours, the liquid will turn a certain color. Blue means you have too little, yellow too much and green is just right. Easy, right?
PS: you can also order the mix and the drop checker as a set, which saves a few euros again.
Did you know that this CO2 tester is handmade from sturdy laboratory glass? This makes the glass extra strong, making it less likely to break. Because that would be a shame, wouldn’t it?
Plus, the glass is nice and clear so the focus is completely on your aquascape and not the technology!

1. Turn the drop checker upside down
2. Add a few ml’s of the indicator mix to the drop checker
3. Hold the drop checker at an angle and tap the edge with a finger so that the liquid enters the “bubble”
4. Now turn the drop checker over & place it in your container
This is actually quite easy. Just look at the color:
Replace the indicator mix at every water change. Just turn the drop checker over & rinse it out with RO water (not tap water, as it may affect the result!). If necessary remove algae & clean the suction cup with some filter wool so it adheres well again.
