2.5gal carbing problems

[Brewslikeaking]

Put 30psi of co2 on a 2.5gal keg of session ipa for 4 days. Tapped it today and its all foam. I was told i needed to shake up the keg first. Its all foam but it settles to a decently favored beer but not too carbonated. Any thoughts? Any way to save it? Also what went wrong?

You over carbonated it.
4 days at 30 psi is way too long.
Normally, for a 5g batch you would do 30psi for 24-36 hours, then set it at serving PSI. It'll be perfect after another day or two.
I've found a day at high pressure is too much in a 2.5g keg. I do 12-16 hours at 30psi.

So just take off the gas and itll be good in a day or two?

I had the same problem just take it off the gas,and purge it every 6 hrs you'll get there in a couple days
