Melly,
 I am not Garrick, but yes, I am using the Big Berkey  with the black elements in top chamber, and fluoride filters in lower chamber.
Once I can work out or have convincing evidence that prill beads take care of all fluoride I might remove the fluoride filters from the lower chamber as well which would take care of  possible aluminum residue. My filtered Berkey water would then go straight into the prill bead jar.

Garrick,
 
Do  you use Berkey? I have a Big Berkey with black element filter on top in the first chamber and the flouride filter at the bottom inside the second chamber. I was informed only 95% of flouride is removed and alumina residues are also left behind.
 
Any suggestions on how to remove remaining flouride and alumina  residues? All are welcome to comment.
 
 
Thanks.
