Nitrogen over foaming

[stevemay55]

Just hooked up Nitrogen set up. I brewed a milk stout and force carbonated using Co2 at 30 PSI for 2 days, let sit for 2 days and then hooked up to nitrogen set at 25 PSI. Using nitro tap beer pours incredibly foamy, it takes at least 5 minutes to settle. What did I do wrong so I can prevent this next time and is there anything I can do now to cure the over foaming?

Having the c02 at 30 psi for two days probably overcarbed the beer. Next time, set it for 12 psi for a week before using the nitro. For now, you could try purging the keg a few times a day until it's not overcarbed anymore.

Thanks for the quick reply Yooper. I've tried purging several times a day to lessen carbonation without any luck. I have found something that works though. If I barely crack the tap I get a very good flow resulting in a nice mostly beer pour with a nice nitrogen head. Is my PSI set too high at 30 or should I use a longer beer line
