I got mine for local, and only experience I have for sand beds are my Nassarius Snail. They seem to be doing the job! I see them out on top @ night as well.
I have one that split in 2. They are cool but if your sand is really dirty like mine it doesn't make a huge difference. I also have 2 conches that look cool
Got most of my cuc [MENTION=10238]Deep Blue[/MENTION] aquariums in north Hollywood. Prices are good and good sizes on snails and sand shifting star fish. When you here cheap prices means your getting mostly small cuc.
