Out of about 21,000 fish... at an UC Davis research center. Hmm... How did the contamination of chlorine happen? Did they not have the de-chlorinator powered on or someone forgot to power that up? I'm wondering if anyone is getting fired over this, it's not a few fish, it's almost all the fish, some even are endangered... People need to double check their work, it's like locking up your house when you exit. Even with a failure in the decontamination system, don't they have downtime procedures or anything else done? Like a backup system in place? Link: 'Catastrophic failure': 21,000 fish die at California university research center (msn.com)
