Is putting something under rockwork a good idea?

I’ve always been fond of placing bodies of ex-bosses under rock work. This usually requires a lot of rock but it’s welcome for additional surface area. However, it does require a large, strong tank with additional bracing in the stand. Oh, don’t forget to reinforce the structure if on a second or third floor.
:beaming-face-with-smiling-eyes:
Best way to cycle a tank.
 
You don't have to take it completely flat, just knocking down the high points and spreading the load out.

I actually took smaller pieces of flat rock and glued them to a few pieces of the base rocks to make them sit the way I wanted. In turn it left a lot of room beneath the rock.

I can't find pics right now but thing of them like feet or wedges.
I can see how that could provide some interesting spaces for gobies and whatnot to make a home.
 
Like the stuff yard signs are made of? Or something solid without the hollow channels?
The material I specifically used, I get in sheets at my work. I’m a prosthetic technician and we use polypropylene to make braces and prosthetic devises. I believe BRS sells sheets of ABS that would suffice. I just didn’t want anything with holes like egg crate due to it being a detritus trap as well as an irritant to sand sifting creatures. Hope this helps!

Yes, thanks. I was wondering if the channels would be a detritus collector. Could also provide homes for critters ya might not want.

I know many people on this forum use egg crate and I even bought some originally, but the flat plastic made more logical sense to me.

I was thinking about small pads of Dri-Dek, which I have under my sump. It'd distribute the weight and since it's lifted off the floor by little posts, there'd be complete flow through the sand -- unimpeded by the walled-off cells you'd have with eggcrate. But chemically, I have no idea how it would affect the water.

Yeah, I’m not too sure about that one. It says it packed with “UV stabilizers”.
