I have used this for about 7 months now. It works great. I've never had any problems with it. The only reason I am selling it is that my situation has changed and I now need to run CO2 on 2 tanks from 1 regulator so I am upgrading my regulator. There is absolutely nothing wrong with this regulator. It has a preset working pressure above 30psi so it will be able to operate any diffuser on the market with no problem. I will include the GLA Atomic bubble counter with integrated check valve as well as an Aquatek paintball CO2 tank adapter if needed.
$150 for GLA Atomic V3 CO2 regulator + GLA Atomic bubble counter/check valve + Aquatek paintball CO2 tank adapter, shipped USPS Priority Mail.
I can also include an Aquaclear 20 or Aquaclear 30 at no extra charge if you want.
