This should hopefully answer both your questions. If not feel free to clarify.
I’m using a 240mm buchner funnel. 25 micron paper in the bottom.
100g bentonite/ 500ml etho
Pull vac pour slurry.
Then
65g neutral carbon/ 500-600ml etho
Keep vac pulling, pour slurry.
122g magnesol/ 500ml etho
Pour slurry, vac still on.
100g celite 545 (or silica) /500ml etho
Pour slurry, put another 25 micron paper on top then filter tincture.
This was good for 30lbs in 13 gal. After that green leaked.
Then i filter that again with 6 micron paper and if needed be 2-3 micron paper.
I might add that this completely removes any water solubles, after decarb there’re no burned particles or charred anything left in the pot. Just smooth crude.
