airline works.

customaquatic @ $0.20 a foot, Marine Depot @ $0.99 a foot. Airline works, but it wastes lots of CO2, it is also soft which causes a delay in changes to the needle valve (due to stretching). CO2 tubing is rigid, so changes to the needle valve are more immediately reflected in your bubble counter. Get a good CO2 check valve, it will save the regulator.
