if you are judging the sorb as "nice clean unused" by the color... that is you are using sodasorb with the color changing indicator, don't beleive it!!!
I have been told by a VERY respected source, as well as observed it myself, after use the color may change back...
I have had near 3 hours on my sorb (mk15... so about 1/2 used)... didn't get arround to diving again, so a week or so later emptied the scubber and ther were only specks of blue...
so just a friendly fyi if that is how you were looking at things...
a great solution is just to dive more!!!!!
