Ok, so a few months ago I decided that I was through with saltwater reef tanks and I wanted to get back into keeping poison frogs. I've been in the planning stages for months trying to figure out the best way to create a large display enclosure, but in the mean time I decided to try out my techniques on a small scale first.
So, I decided to build an 18x18x24 vivarium. This one is actually built out of 3/32" glass, but if I were to do it over again I would build it out of 1/8" glass to make measurements easier. Feel free to ask any questions about the techniques used 
Day 1
The bottom, back and both sides are in place. Painters tape was used to hold the pieces in place.

Day 3
I let the tank cure for 24 hours and then water tested it for leaks

Day 4
I siliconed the aluminum rail in place to support the door

Then the door is test fitted and secured with 4 1/2" x 1/8" rare earth magnets. The magnets are placed so that one is inside the vivarium and one is outside the door, so it is glass on glass in between, essentially fly proofing the door setup

Day 5
I had to wait for a 1/2" diamond hole saw bit to come in to finish the top, so I started on the false bottom construction first.

Day 6
Installing the mesh screen. I went through 2 versions of this and aren't happy with either. The first isn't fruit fly proof

And the second is too difficult to work with, and as such is too messy
