Calgary zoo rays die due to human error

[Tarolisol]

You would think for such a large publiic exhibit testing dissolved oxygen would be a daily duty

Someone somewhere dropped the ball on building and designing that enclosure.

Not the first time a zoo has killed aquarium life, a zoo in Indiana not long ago killed most of their sharks by over dosing ozone.

The question that needs to be asked now then:

Since the exhibit has re-opened (albeit without touching/feeding) have they rectified the design issues, or at least bought a profilux

Although highly unprofessional, it's cases like this where I think about all the livestock that dies daily in shipping and in the hands of amateur (and experienced) and "experimental" aquarists.

+1, though a zoo should know better.

This is way different then that. A zoo charges for addmission and is expected to know at least something of the species they keep

My guess is a mag 3 pump with a rena air pump and one of those circular air stones.
