Why is my CO2 checker not changing color?

Firstly, If you confirm that your co2 drop checker solution quality good and the co2 drop checker position was the right level, usually there's a delay of about 2 hours - this is how long it will takes for your drop checker to change colour. So if you tweak your CO2 levels now, wait 2 hours, then see what colour it has changed to.

Where is the best place to put a CO2 drop checker?

Put the co2 drop checker below the water surface within the aquarium and where CO2 bubbles from the diffuser are least likely to enter the device. Leave the drop checker in the aquarium permanently. Please remember that never put the drop checker in a dead zone regarding water circulation, as it will not provide readings accordingly and correctly with the CO2 you inject.
