Sorry for the total newb question. I notice the connection on the false bottoms are 3/8" while the connection to the inner part of the manifold is 1/2". Will this work when connecting a tube between the two or does one piece need to be modified to either 3/8 or 1/2? and which is better or more efficient when pulling wort, the larger or smaller tubing. Didnt know if it mattered or if there is a more ideal size. Thanks for looking.
