not if it stays in your tank…it needs to get involved in the actual extraction to effect color.
if you do your reading you’ll see that “dark extract” is one of the commonalities that bring folks to exploring their molsieves. the other is having ice get in their way.
possibly, although this is going to depend on system configuration. I could certainly set a system up either way…
however, the more efficient setups have a cold condenser on the way to the solvent tank, and getting ice in there will generally bring you to a dead stop.
…and how often have you been regenerating the beads?
do you know how to test them?
