Huh? You know that Basalt is a volcanic rock dust but you read that 'lava dust' is absorbed faster?
Huh?? Redux.....
I'm not even going to touch the absorbed - I believe that you meant to type adsorbed, right??
Absoportion vs adsorption is a difficult concept for many. I had a hard time understanding it when I was first getting into aquatics and trying to grasp how the adsorption properties of good activated carbon make it a form of chemical filtration.
