Well I hate my sand, so put me down for BB.

I would switch it in a heartbeat if it wasn't so hard to do.

The key is bioload and balancing your waste management. High bioload + a Sandbed is a recipe for disaster in the future. Unless of course you are the worlds best water changer. A sandbed will mask your high bioload problem until it no longer can, and then you're in for some major problems.

Having no sand will not mask this problem and you'll be forced to deal with it before you have major long lasting problems.

Flow is the other area of concern, 'high' flow rates are not possible using sand as it won't stay put. Flow is the #1 overlooked important thing in this hobby, water movement makes everything possible. Stagnant tanks aren't good for much..

All above is very well said.
No3 will accumulate in a long run even with water changes.
Flow is very important.

BB here also.

Sand is a real PTA with the 50X flow in my tank. I only have 1/2" to 1" for looks, and I'd ditch it in a heartbeat if I didn't like the look of it so much.

Running my 75 with a full load of SPS, 5 fish, 70# of rock and no sand, I had 0 NO3 every time I measured. No gadgets, no NO3 removal stuff. 10g water change every two weeks, Ca reactor for Ca/alk and nothing else. No Mg, no supplements, etc. My tank did just fine and grew faster than I wanted it to. The BB allowed much greater flow than sand would have allowed, which results in thicker SPS growth. After 6 months the bottom was covered in coraline and such anyway, so it looked ok.
That being said, I miss the times sitting in front of the tank at 3am with a flashlight watching all the cool critters from the sand bed.
My new tank will have some sand for decorative purposes as well as giving me back some of those critters. I do not consider sand neccesary for NO3 removal, but that's just my experience. I would never use a DSB again, as I feel this is just a time bomb waiting to kill the tank. Might be 4 or 5 years down the road, but it will go boom. Again, YMMV

That is a heavy bio-load, and with 3 feedings a day, ya, you might get a nitrate problem.

I had 2 tangs that grazed on tank stuff, a pair of clowns and a chromis. I feed once per day with mysis and added about a 2" x 4" strip of nori for the tangs.
Honestly, some of the nicest tanks I've seen used only a skimmer and reactor, good lighting, minimal feedings and were with or without sand. Sand never appeared to be the deciding factor in a nice tank, rather stability, frequent water changes and minimizing nutrient input.

thanks Brad I didn't think that feeding flakes 3 times per day would have a impact on the nitrate problem. I guess i will shorten the feeding down and figure out a way to maybe get rid of some fish I was thinking of taking out the purple tang. and the foxface may be

Aesthetically speaking I like BB in small tanks, its kind of like a minimalist look in a way. However, I think when I set up another large system I will go with a sandbed for looks more then anything.
