Adding a sand bed at a later time.....

[morecowbell]

I want to do the same thing, however right now my tank has about 2-2.5" of crushed coral on the bottom. I got it on recommendation from lfs and thinking I'd like it but it's been in there for 6 months now and I hate it. So how do I go about removing it safely? I have a 65g.

Should note that I do vacuum a selected area whenever I do a water change. So vacuum say 1 corner, and next change do another corner.
