Is this a new/fairly empty tank? When I 1st added sand I would stir it up and use a powerhead to get the fine sand, that is easily disturbed, into water column, allowing filler socks stuffed with filter floss to capture most the fine particles.. this way, later on, I don't have a big sand storm everytime the sand bed is touched. Took a couple days to clear up, never had a sandstorm again. I don't think a tank full of corals will like this very much, nor should a well established sandbed be disturbed this way. Not sure of your current situation(tank age, inhabitants, circulation or mechanical filtration.) I did this on a very new tank with live sand that I didn't want to wash the life out of.
