I just started making my first batch of fina. I mixed the oil with the crushed pellets and BA, swirled and then let settle. It looks like there is 2 layers of sediment on the bottem of the vial, one that is redish brown on the bottem and one that is whitish brown on top. Is this normal? Should I go ahead and filter it. I am a little woried. The article at gotfina said there should be only one layer of sediment. What do you guys think?
