Ya that tread almost made me order a nuvo, and I've never been a fan of AIO's. And no I would never use crushed coral, mainly because it promotes the destruction if natural reefs which kinda makes the hobby look bad, not to mention that it traps detritus. Most of the black aragonite is pretty heavy sand IME or just a heavier of what ever color you choose
