Substrate.....or no substrate?

[mark]

I'm BB and liking it. Had shrimp and kept a Blue Linkia for about 2 years and about the only thing that probably wouldn't work, that I would want, would be that burrowing goby/shrimp pair. Found the bottom doesn't stay bare for long as get covered by coralline and zoas but is still easy to clean.

Still think it's something how long it takes people (including reefers) to notice no sand. If your not sure what to do can start BB and always add sand later if you don't like the look. If you do go sand suggest you consider just a SSB.
