I borrowed a recipe from a friend to make a Wit Beir and entered it into BeerSmith. The resulting recipe hit all the numbers he gave me for OG, IBU & SRM. So I thought cool, all I have to do is hit the convert button, select my equipment and hit OK. Well it told me I needed 59 lbs of Carafoam and 110 lbs of Rice Hulls along with the rest of the original ingredients minus the other grains. WTH? I tried it several times and it just won't work.
