Thanks! I've read that before about aquarium charcoal. I need to remember it for next time.I bought a bag on Etsy that reeked of perfume. And it was undisclosed! 😡 I put it in a lidded plastic bin with several bowls of aquarium charcoal. It took over a month, but eventually the smell was gone. Of course, it may not have been as stinky as your bag.
