Substrate.....or no substrate?

bare bottom is easier to keep clean, as well as safer in terms of "Old Tank Syndrome", when deep sand bed accumulates so much dirt that tank is polluted with Hydrogen Sulfide and everything is dead in very short period of time.
If you really want sand keep it at 1" inch level.

I've run everything from BB to DSB and everything in between. Frankly I think BB or super shallow sand bed are the way to go. Easy to clean and, as has already been said, will soon be covered in Coraline or zoas so you don't really need to worry. I've even seen one tank on RC that had pretty much a "lawn" of GSP.

The only reason I'm going with a super shallow sandbed in the 20 gallon is for looks...there won't be a goby, but will be some sand sifting snails.

Either way you go will determine how you're going to secure live rock for display.

Hope this helps!

Cover the bottom with zoas, acans clams etc then you won't have to worry about seeing the glass. If you'd like to see an established BB tank you're more than welcome to come have a look...

I'm of a different school of thought from just about everybody on this board

As far as I'm concerned detritus is your friend, it is a food source for many different filter feeders and corals so I have a 3" sand bed that is undisturbed (except when I lift a rock). I have been successful so far and my tank will be 5 yrs old in march

take a look at the first couple of pictures in this thread for a GSP-bottom

Thanks, everyone, for your feedback....still haven't decided what to do, but I am less confused by all the options!

I am gathering from various posts that one reason to have sand is to keep the aquascaping secure. However, I have read that the rocks should go on BB rather than sand, since pockets can form between the two if the rock is place right on top of the sand. True? If I go BB, how do I keep my rocks from shifting?

Anyway, still debating....I like the thought of having sand-burrowing critters, so it will probably come down to that.

Xtreme, could you post a picture of your established BB tank?

My rocks directly on the glass and don't move.

If planning sand don't place the rocks directly on the sand as will settle and shift. What I did when I had a DSB was make platforms out of egg-crating and zip-ties so the bottom 3-4 inches of the rock wasn't buried.
