So, given the scale of this endeavor and the finite resources available, I need to be creative.
One idea is to only use 3 sheets of expensive 3/4" starphire glass: side, side and front - in the shape of the U
The back and bottom are probably viable in another medium- plywood, concrete, plastics...
So - question to all the massive tank owners with experience doing multi-modal builds : what do you recommend?
I have experience with plywood and epoxy. I've also done cinder block and epoxy. In both cases, I used plastic windows with silicone that acted as a gasket only. The frame for the acrylic was made of the construction medium covered with epoxy.
I've never used glass and another medium.
Also- the two ends (bottoms of the U) should clear silicone without metal or wood bracing.
Thoughts?
