Sorry that it worked out that way for you. Don't know why or how.
I've kept discus for many years in planted tank environments, and have been using Purigen 24/7 in my discus tanks for several years straight.
Have re-charged Purigen up to 15 times with no ill effects, or no real loss of clarification & purification effectiveness.
Once the particles have returned to their normal white coloration after 24 hours in a 50/50 water/bleach solution, you simply have to rinse it well and let it sit in de-chlorinated tap water until you're ready to use it again - no problem.
Please do try it again.
