I recently bought a dual tap kegerator which comes with a 5# CO2 tank and regulator. I already have a 10# CO2 tank and regulator that I use with my single corney keg. Ideally I'd like to hook the 10# tank up to the two regs so I can serve beers at different pressures or carb one. Any thoughts on how to set this up? Can I just run one off the other and adjust pressure that way?
