Derek,
Like Ed said its all about the layering of the great stuff. The 10 gals that you have are prob aquarium tanks. If you buy the terrarium tanks the glass is thinner so they may crack. Just make sure you leave room for the expansion of the greatstuff and you can always go back into to seal corners and edges. We are making more of our thumbnail verticals now as well and this is the way to go....so many possibilities.
