I used Purigen once, and it was very effective. I tried to follow the re-charge instructions I found on the web, including multiple sessions of rinsing and treatment. When I tried to use it again, my ecosystem crashed.
I'm sure if you were good at chemistry, you could recharge effectively. However, I think most people use Purigen and then throw it out, adding to the micro plastics in water.
