I can understand the article but there a couple of things that I will do to help mitigate any possible problems. Every water change I plan on "cleaning the substrate with the little water suction cleaners which should get a good bit of the detritus out. I also will be incorporating a bio-denitrator to help keep down nitrates. The last thing is to keep a pretty aggressive refugium full of chaeto to help maintain the water quality. And if worse comes to worse, i'll take it out and put in sand.
