Title should read "carbonation stone"
Recently we got a DO meter worth its salt (the Hach orbisphere), and found our FV DO readings to be unsightly high. Anywhere from 180-300 PPB even for beers that have not been dry hopped or the tank opened. Then I started thinking my only suspect would be the carbonation stone check valves we've been using. I replaced them all with SS plugs, and Viola! our tanks are reading the same DO as a 2 month old can of Coors now! Just a heads up for those without a DO meter. These are Check valves that we received with our stones when we bought them from GW Kent
