Which drop checker you using? Did you add in the correct drops of CO2 test? What is your water pH?
do you use ADA Aquasoil, peat or other thing that change your tank water paramter? if so did you use kH = 4?
ok guys i found out the problem , it seems theres a layer of slime covering the drop checker as seen , i suspect my anetome helenas for that but any idea why they do that ?

anyone care to advise ?
are you using DIY CO2? I only see that kind of stuff when I used DIY CO2.
unless you are injecting a large amount of dissolved CO2 into tank else the swings or difference between CO2 on/off will not spark a colour difference in your indicator.
