Recommendations for disposable CO2 setup for 2.5L
I'm looking for a disposable CO2 cartridge setup. Must have regulator, diffuser, and bubble counter. This will be for a 2.5L tank with HC only. The tank is on my desk, so I don't want to make a 5# setup. Simple and sleek is what I'm aiming for. Minimal clutter. Any suggestions/recommendations?
