With considerable help from Fabman and Kennedyford, I have finally succeeded in producing a good 25 gallon batch of BD. It was not without problems however. I had trouble filtering out the Magnesol but finally succeeded. I have since ordered some 10 micron bag filters and hope that after filtering through it using gravity feed, I can filter through a 5 and 1 micron filter using a pump without "sheering" the magnesol. Any comments from you guys? Thanks very much FTE and the aforementioned helpers. Tom
