Hi...

I just changed the CO2 indicator solution in my JBL permanent tester and found that the colour is not changing. Has the solution "gone bad"? I remember putting on the cap tightly the last time I used it. sigh

Is it you mean no color or what color. Normally it will take 2 to 3 hrs to stble then it is okay.I also once have this Problen when i notice at the bottom of the indication bottle got air sangkut n block the whole breathing hole.

Can u trust this little thing? I used to have one but don't feel it is right. Sticking with KH-pH method.
