baron von bubba said:"Purigenâ„¢ is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigenâ„¢ controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. "
and this is a good thing? obviously removing ammonia is good but how much nitrate does it remove??
For freshwater use, soak for 4 hours with a solution containing 1 tablespoon of buffer per cup of water (Discus Bufferâ„¢, Neutral Regulatorâ„¢, or Acid Bufferâ„¢). Original color and full activity should now be restored and Purigenâ„¢ is ready for reuse.

I use a pH 6.5 buffer solution, simply because I don`t know how rapidly the pH would change. I appreciate that pH isn`t as significant as people think, but a virtually instantaneous change may well harm my fish. I am just hedging my bets a little.
