Dissolved oxygen was low? In a touch tank?

 

:huh:

 

 

 

Yeah.

 

 

I mean, if they had an air shield, then they wouldn't have been vulnerable to megamaid, now would they?

With an 8' tall 6' diameter protein skimmer in line with filtration to the same open touch tank pumping in COPIOUS AMOUNTS OF OXYGEN in to it no less.

They must have made the password too easy to guess.

I always wondered if someone ever thought about doing that when i go to seaworld.

They have a ray petting pool also

I suppose it wouldn't take that much chemi-clean to treat that much water... if 1g treats 150gals of water then you would only need 67g to treat 10000 gals. Of course you would have to overdose it a bit to get it to kill all those rays in just a few hours. So probably 120grams at the least. Also you would think it would show up in their analysis. I wonder if there are other chemicals that could lower dissolved oxygen dramatically.

I say chlorine that they probably used to clean the tanks before introducing species....

 

As far as "StingRay City" the only one I know of that DOESNT KILL is in the Bahammas that I visited... TOTALLY BA... I was younger, about 10, and got to feed them, snorkel with them, grab on and have them swim me all over... AND I DIDNT GET STABBED IN THE CHEST!!!!!!

 

Screw captivity of large creatures like that... Just not right..
