So I'm trying to redo my Aquascape as I've never used any type of epoxy or anything like that so I wanted something unique and different for my tank. I need some advice though as I'm trying to follow the rule of thirds and this is what I have so far and I'll also take a picture of some of the other rocks I have including one that is almost a perfect arch that I really want to use for the scape. Any advice or a contributions to help me would be greatly appreciated.
