fluval edge mod

yes i will definitely check and make sure that the substrate stays put, i dont think it would take too much to turn that little tank into a giant cloud of dust, ive read up a tiny bit on substrates, no one seems too crazy about the crushed coral substrate, mostly cause of the lack of surface area compared to fine sand, and there were some complaints about debris being trapped in there, should i rule the option out? is it really much worse than sugar sized aragonite etc?

and im not a crazy flow monster, im just an amateur reefer who doesnt understand limits
