Hi, i have a few questions about this mod. First should i reduce my co2 levels to 0 or always keep some around so the recyclers work at full capacity? If i start getting high co2 levels or low o2 levels, is there anyway to be warned or do i need to regularly check up on my ships and bases? Last what is the best way to have a auto sufficient base or station so i dont need to keep refuelling o2?
