Ok im putting together my 1st wc setup. Orderd 1/2 inch tube and barbs, and as i was looking at them i realize that the barbs and fittings are much smaller than 1/2 inch ID. Is it common to use the next size higher to reduce the flow resistance? Or does it make such a small difference that its not worth doing?
