I have left it for 1 month no problem, when bad weather hits! but normally 2-3weeks!
ditto on that. and I leave the canister out overnight to dry excess moisture and then bag it. As far as reusing sorb, time between dives is not nearly as critical as depth and time on subsequant dives. I tend to do my deepest dive first, then subsequant dives shallower, paying attention to work load as well.
What i've gathered so far, is that as you go deeper and the gas becomes denser, co2 can pass by more granules of scrubber as it goes down the stack before getting "captured". This spreads the reaction front out, deeper into the stack, making it more diffuse and reducing the portion of truly unused sorb disproportionately. by making subsequant dives shallower, you safeguard against what would otherwise be an unpredictable point of breakthrough.
ahh, that's how i think of it anyway
