I inject CO2 into my 5 gal planted tank with nano regulator using 95g disposable cartridges. These are expensive and need frequent replacing. I would like to convert to refillable tank but because of space restriction, I can’t use the common 20 oz paintball tanks (which are 10.5” long). Does anyone know of a shorter refillable tank?
