Hi do I need to keep the gas on my keg as it was producing just foam I was told to put 30psi in the keg for 48hrs degas it and apply 12psi so sone that left it for a week went to pour and got nothing but foam so I turned the gas of and degassed the keg left it for a couple of days tried it again and got a great pour of beer it’s been in the fridge so I don’t know should I put the gas pressure back up to 12psi or just leave it until I’m ready to pour again and apply just enough pressure
