Sad News from the Calgary Zoo

[Patrick1]

My 2 Cents,

I wrote earlier in this thread that I spoke with the (expert). Thinking I was going to get some deep insight into the world of rays. Not the case. So why did they die? Well no one poisoned them. The water tests for nitrates etc, was good. The equipment was all working but, they still haven’t come foreword to say that there was no pollution. Lets face it even with regular water changes 400 hands in the tank an hour is going to be a problem. The zoo even said they didn’t check for pollutions. I am going to go out on a limb and say that the complete water tests showed something was in the water (not deliberately) but it has to be there and the zoo wont say what. My vote; A whole bunch of greasy hand pollution.
