Just a hypothetical question for a silicone blow off tube (ID 9mm OD 13mm), at roughly what rate would the blow off tube filled with 100% CO2 diffuse to atmospheric air / O2 and then eventually be fully replaced.

Let's assume the length of silicone is 1m, the internal length of tubing holds 63.6ml of CO² which (I think) would roughly equate to (1.847mg/ml) 114.514mg of CO2 at 15C.

Also by all means if my maths is completely incorrect please change it 🤣
