sand over crushed coral - can it be done?

[Aquattro]

Patrick, when I converted my 45g to a reef, I siphoned out the gravel 1/3 at a time and replaced it with sand. I waited 2 weeks between sections and six weeks later I had a complete sand bottom and no cycle. I was a relatively simple process. I think putting sand over crushed coral might create a detritus trap which would be bad. Maybe check with Ron Shimek at reef central.
