Move bag around some to allow flow to all the media.
When Purigen is completely exhausted all beads will almost be black.
I regenerate when all the media is a good brown color.
The more dissolved organics in your water the quicker it changes colors.

I have tested other organic scavenging resins in the industrial market place with different regeneration methods.
Purigen seems to be the real performer for the aquarium even though bleach is used to regenerate.
