We have always had a crushed coral dsb. Never had any problems. Always found it easy to clean. Currently have a 3" sandbed and would never consider having any less. We have a wrasse that likes to bury himself in it and loves it. I would never use a sand bed as it would be a nightmare to clean. I am sure that you have noticed by now that there are always people on both sides of the debate. I am just simply telling you what has worked for us.
However, if you do decide to sell it, put it here on ARC as there is always someone looking for it.
