I keep a volitan lionfish and snowflake moray in my 120gal with only a 1" thick sugar sand bed. I used to use crushed coral but I really didnt like the look of it. The large particle size tends to trap and hold a lot of detritus. But if you plan on keeping it and dont want the hassle of siphoning each week you could remove some of it so that you only have a thin <1" layer. Then just give it a stir once a week and let your filtration pull the gunk out.
