A simple question regarding the mixing of O2 with Co2 from pressure fermenting. I have a Spike Flex + and I pressure ferment lagers and spund ales for the free carbonation. So, I have a Spike PRV that has a cup for sanitizing solution through which any C02 beyond the 15 psi that the fermenter holds passes through it. The question is: must I fill the cup, so that when it is releasing excess pressure/CO2 no O2 can mix in with the CO2 within the fermenter?
