Last thing i can possibly think of is if the pipes to the questionable classroom or sink were old lead ?
 
Really gutted for you mate

The building was built in 2001.    Thanks for trying though.  I appreciate it, honestly.

A little impractical i know, but it would be interesting to see what would happen if you took the tank home and tried it there.

My wife would kill me!

I found the story below on another website. I know it's gross, but perhaps it's possible something like that was happening to your tanks? You said even the fish in the small tank died?
 
"Hello; In 1998 I took a position teaching biology in Brunswick County NC. I had to rent a room and could not keep my tank there. I set up two tanks in the room where my biology classes were held. I made the mistake of letting the students know the fish were my personal fish. Over time I found several things in the tanks and eventually someone put something toxic in and all the fish died.
Among them was a kuhli I had kept for around eight years as near as I can calculate. I was out of fishkeeping for about six months after that but kept my tanks."

That thought has crossed my mind.  I just don't know what they could have added to the tank that would have affected everything but the cories.

 And they would have had to add it when I set up the 10 gallon as well... months later.  The cories are in the 10 right now waiting for September.

It could be anything. Corys are tough fish.

I wouldn't put it past a naughty kid to do that, but they would have to be awful crafty to sneak it in there every go around, and also to find something that you wouldn't be visible once added to the tank.

Wow, I've just finished reading all of this. I'm so sorry for all that's happened. It must be so disappointing! Try again at the end of the holidays though, hopefully everything will go better next time!
I wish I had something to suggest that could have happened to your tank.

 

[eaglesaquarium]

Thanks Blondie.  Yes, disappointing is a good term, but I believe frustrating is the proper term. 
 
Trying not to think about it currently... taking a break.

 

[Blondielovesfish]

A well deserves break it seems!

Frustrating is probably more accurate!

Nice tank!

Awesome.

 

[eaglesaquarium]

Thank you... the tank is nice.  Everything that has happened inside it has not been so far.

Dear eagles.
 
If you steal my puppy.. I get your tank..

I am heading in the direction of taking the plunge with this again, but I am dealing with a current money drain right now due to some other things happening in real life.  Needed a repair to A/C unit and its going to cost over

!!!  Money I really don't have to put there currently.

 
 
Anyway here's the current hardscape...
