Filtration through AC and T5 should be all you need. I use it regularly and am super happy with the results. I make a slurry of the bentonite with ethanol to make the puck (on 6" filter plates). I then do the same thing with the AC (we use hardwood). 1/2" to 3/4" for the bentonite layer and 1/8" for the AC. Seems to do a bit better when we filter cold but have achieved the same results with warm filtration as well. This is what 3 passes should get you:
Edit: Spelling and grammar! Really need to proof read better sometimes. Haha
