I thought people were getting 50% recovery. The first batch might have been a little more than 25 gal it was the first time with my tank and I didn't mesure the amount going in. The glycerol was in a bunch of cubes, some filled more than others.
Another question?? When the glycerol is cooking my sight tube has mostly a clear liquid in it with the brown glycerol at the bottom, but when I drain it it all comes out brown-no seperation. What's the clear liquid??
