I held off trying sand for just this reason. And there is validity in the compaction issue, if one is not careful. Any substrate will compact, and the finer the material the more it compacts. But plant roots (substrate plants) work against this, as do Malaysian Livebearing snails. My sand substrates are shallower than my gravel used to be.
