I would not worry about having a little crushed coral gravel in the
sand. Actually the bristle worms prefer rock.

I pulled out a 5 gallon bucket of crushed coral. In a sand bed loaded
with detritus, I found two small bristle worms. That's it. It's been
my first experience with a DSB and it hasn't been a good one.

We'll see what happens this time around. I'll give the sand bed a few
months and then I'll add some detrivores back in.

My 110g I run with just a shallow sand bed of maybe 2-3 centimeters. So
far, I like that approach better.
