I actually ordered some sealant this morning, so I'm waiting for it to arrive. I have 2 issues with Canvas.
1) It would be almost too bulky for small tanks like mine.
2) Does not work on sand (I tried lol)
So for the time being, I'm doing perler "tile" floors, and gluing gravel on top to keep it down. Once I get the sealant, the rocks could probably go on the bottom of the floor piece to offer a smoother place to rest on.
Also, a bridge is a neat idea!!
