Sand bed indecision...

[Aquattro]

I went with about 1.5" of sugar sand in my SPS tank. I've since replaced it with a little heavier grade. It still moves around to the point that the front 4" of my tank is bare bottom. I have wrasses that like the sand, so I keep it, and I also put egg crate down below the sand because I'm dumb sometimes. If it weren't for the egg crate, I'd remove it all and add a big container of sand behind the rock for the wrasses to sleep in. I do like the look of sand, and it stays clean, but I currently have a mix of shallow, deep, bare and egg crate bottom. Le sigh....
