Yes... but I don't completely release all of the pressure. I press down the poppet until there is only a little bit of pressure remaining, because I am afraid that if I completely equalize the keg's pressure with the atmosphere's pressure then I will get a little bit of oxygen sucked backed in.
I connect the CO2 QD, pressurize keg to 30 psi, disconnect the CO2 QD, and release the pressure (not all of it) 3 times before force carbonating.
