Alright so I am wanting to redo my fish tank as I am not really happy with it. I currently have gravel in as the main substrate but I want to add a sand "river" in the tank, possibly on a slope. Do I need to use some sort of substrate divider? What can I use as a substrate divider if I need one? Any help would be greatly appreciated!
