can't help but agree with this whole-heartedly.......I started a bare-bottom tank a few months ago just to try it and see how effective it is, and I have never had such an easy time cleaning. Considering various substrates to give it more body and character but sacrificing that easy-cleaning for anything just seems not worth it.People normally do tile or keep it barebottom for easier clean up, I feel like this would take away from that as debris will still get stuck in between the rocks. I also feel like that would be too rough on the fish. I know especially with Africans they'll scratch from time to time on the substrate and this would probably hurt them. I'm sure no bottom dweller would appreciate that as a substrate as well
I achieved that on my 75 gal by using large black trash bags, attached on the outside with tape.I would like to have a black bottom and back w/ little gravel baskets for plants
