Scott, one relative indicator is to set up a small tank with a proportionately small
activated carbon filter. Pour in acriflavin dye, the charcoal will remove the dye, either
completely or almost completely. You can repeat this until the charcoal no longer
impacts the dye. It's a layman's approach, but gives a great visual on what/how
much the charcoal is doing.
