That's actually just a fluidized media reactor with fine sand in it. They are used in FW and serve pretty much the same purpose as bioballs in that they provide surface area for nitrifying bacteria to colonize. Given that most reef tanks don't have issues with excess ammonia, I don't think they will do much for you.
