Does anyone try to remove atmospheric CO2 when filling your diluent tank? Most dil mixes, as I understand it, are just filtered air @ 21%, or if Trimix air + helium. However air is already ~0.05% CO2. You’re carrying that down just to have the scrubber absorb it.
I guess that really doesn’t matter relative to the metabolic respiration, after all you’re going to convert the ~full O2 tank to CO2, while the dil will mostly circulate and only <=0.05% was CO2 to begin with…
