Hey, Im selling one of my co2 tanks, It is brand new never been used but it is filled, with decals for transport. Great looking tank and LIGHT!! not like those heavy steel ones that are also quite ugly with the paint. It comes with an aqautek cool touch rego, has dual gauges on it, a flow meter for hydroponics, solenoid, and a brass bubble counter with check valve addon. Very pretty rig, and very practical for your planted tank needs, Or brew kit/hydroponics. Throw me a text to come see it!
