FZONE Mini Series V3.0 Dual Stage CO2 Regulator

Brand: FZONE

The Mini V3.0 is a compact dual stage regulator made from hard aluminium alloy, sized to sit on a paintball cylinder or a CGA320 refillable tank without towering over the aquarium. A 12V DC solenoid, a bubble counter with check valve and the installation tools come in the box, and the needle valve is fine enough to settle at one bubble every few seconds for a nano tank.

The obvious choice for desktop aquascapes where a 5 lb cylinder simply will not fit under the stand, and for anyone who can refill paintball tanks locally. Downsides come with the format: a 20 oz cylinder empties quickly on a larger tank, and the small gauges are harder to read than full size dials. The cylinder itself is not included.
