"Rex Reactor" for DIY CO2?
I'm looking for information on using a "Rex Reactor" with DIY CO2. I've read many posts about building the reactor, but I'm not sure if it will work with DIY CO2. My concern is that pressurized CO2 is needed for this style reactor. Can I just use a check valve to prevent water from ending up in my DIY CO2 or do I need to build a different type of reactor?
Thanks in advance
