just an idea i had now that i have a 3d printer
& love textured back walls/ reef wall scapes
picture this
3d printed back wall (multiple sections depending on printer size) of a cool scape with some parts jutting out or small caves
then using a safe adhesive (not sure which) to put super fine grain sand over that with regular sand/ small rock and coral bits mixed in to make it look more natural
how doable it is im not sure but i think the idea itself sounds really cool and would probably be easiest for standard size tanks and AIO
