I would have thought pulling air through the collection cup would mostly negate the need of a CO2 scrubber since you are using 'recycled' air. I do it on my mega skimmer primarily to prevent the mazzei injectors from getting clogged with salt creep.
Prevent the need? What do you mean? How does just recycling skimmer air remove CO2?
