Stop Bath rotten egg smell

Matt King, you're an OK dude. Each to his own. To me, a darkroom is sights and smells, and sometimes taste, like developer on your fingers. It's a magic that a digital camera, a computer, and an inkjet printer can't begin to compete with. When I get to heaven and the head man is looking for photography and radio voluteers, I'll run to the signup desk. They took my Kodachrome away, but not my stop bath. Citric acid is for lemonade.

My Adox Citric Acid stop bath smelled really strong of rotten eggs yesterday.
This was a relatively fresh mix. Ran at lost ten 5x7 through.
I’ve never had that problem before with Adox or any other stop bath.
Dumped the mix and washed tray and bottle and mixed up a fresh one. The smell is gone now even after two nights of running prints through.

What could’ve caused this smell?
Decontamination?
I use distilled water for chemicals that I reuse. I also tone in Selenium and use HCA.
