Sand bottom vs No sand on bottom

[PotRoast]

Can someone summarize or point me to a past post/discussion regarding using sand or not using sand in a reef aquarium?

I very much like the look of a black acrylic bottom, but need more info before I proceed in that direction.

not sure if i looked at that post but they say no sand bed allows you water flow to pass under and thru your live rock better and preventing dead spots

depends on your preference some just dont like the look some do

The bottom won't remain black. It will get covered with coralline (or green algae :D).
