The point is
-NONE OF THE SOPS ON THIS SITE SAY TO PREWASH YOUR MEDIA.

This one certainly lists the correct way to set up a filtration over magic dirt…

@TheLostBiologist

Now, for the pour-- Get the slurry in your bucket very well agitated and flowing then quickly dump the slurry into the buchner on top of the filter paper. Use a bit of reserve ethanol to rinse out the remaining bentonite and dump it right into the buchner as well. You will get a bunch of bypass when you first pour. The reality is that even with a paper filter the clay is so fine that it will pass through. You basically need to overwhelm the filter with clay so that it backs up enough that the clay builds up on top. Then it becomes self-filtering. Once you’ve set a good bentonite cake use the same ethanol and bucket to make an AC slurry and repeat the process. If your bentonite cake is solid then you should see no AC in the vacuum flask. You want to use enough AC that it makes approximately 1/8th to 1/4 inch layer on top the bentonite. You can use more and go thicker to gain longevity with the filter, but you will lose speed and increase the time your extract spends in contact with the AC. I usually pour the same ethanol twice for the bentonite then again for the AC. The first pour is muddy brown, the second pour is cloudy, and the final pour is crystal clear. Once it comes out clear I leave the pump on for an hour or so to dry out and firm up the cake.

Which is the way they teach it in chemistry classes last time I checked (admittedly more than 30 years ago).
