Is anybody out there using DE with their gravity filters, or is it strictly used in filter presses? The reason I'm asking is that I occasionally notice some slight cloudiness in my syrup and am wondering if DE could help. I use 4 pre-filters and one felt on my 4-gallon canning unit. I often need to lighten my syrup, by 1-2 brix before bottling. I use sweet from the flue pan for this, feeding it through the filters. Could this be loosening up some of the niter in the felt and carrying it through into the syrup? Would DE help prevent this? For what it's worth, I bring my syrup to 190F (direct propane heat) in the canner before bottling.
