Barrie, John from Brown University suggested a temperature array to determine when your scrubber medium is exhausted. I have an easier way. When you feel like you can't breathe fast enough, and you start seeing stars and black pin-holes in your vision, and your head begins to pound like a drum - your scrubber is no longer any good. I myself have performed this test on a 240' dive. The headache lasted about 45 mins, and went away slowly. I don't recommend that everyone try this - just trust me. Kevin.
