Thank you for your kind comments.
Regarding the construction of the tank. I'm not that familiar with the process since I ordered it through a colleague and had it delivered.
This is what I do know:
you create a mold from wood and cover it with fiberglass mixed with a jell coat. since the mold is on the inside, the inner walls come out smooth while the outside is textured. The frame of the is reinforced with metal as well as extra bands around the tank. The front end actually has a frame about 7 in thick and the glass is glues to it with silicon. What we did was lay the tank face down, applied a generous amount of silicon and placed the glass on the frame so it was overlapping. we let it sit that way for a couple of weeks. The silicon is more of a sealant in this case as the water pressure keeps the glass in place. as for the thickness of the tank, I can only estimate it at around 0.25 in.
I am still waiting for the cycle to finish, but anyway I'll be traveling during April and I don't want any livestock in the tank while I'm gone (NY next week and Disney World in 3 weeks time).
