You have to siphon the crushed coral clean when you do water changes, or the detritus trapped within can cause nitrate spikes. This becomes a pain, plus it makes it difficult to have some of the the beneficial microfauna if you keep sucking them out of the tank.
Are you sure you have crushed coral? Aragonite is about 1-2mm in diameter. Crushed coral is usually much larger and looks like mashed up seashells.
