I dug out my scrubber with a spoon after a days diving and the posts 1 & 4 on the above show the results.

Apparently a Submatix has more of a 'core' penetrating through the centre of the scrubber [defeats the objective of the transparent cannister and colour changing sorb a bit!].

I wouldn't turn a scrubber around as you wouldn't get a lot more use out of it. The gas travelling past the grains doesn't leave a shadow where it doesn't interact in some way with them, and while not all the grain may be used, it wouldn't be a known fact as to how much life there was left.

The warm spot in a scrubber is an indication of where the reaction front is. I found that the Drager Divesorb gives a very [1 inch/25mm] small band that is easy to track and 797 gives a broader band. I have only used Spherasorb a couple of times, so I can't remember how that fared, but I think that it was fairly diffuse.
