    Nope. For saltwater, under gravel/crushed coral filtration has been out of style for over a decade. Even if you vacuum it weekly you'll experience deitrus and nitrate buildup. Corals and a good number of saltwater fish really struggle to thrive under those conditions.

    I'm referring to actual broken rocks gathered from actual reefs in foreign countries. Like this: http://premiumaquatics.com/aquatic-supply/Liverock.html

    It's really porous and filled with beneficial bacteria that will actually filter your water through the nitrogen cycle. Additionally it often brings a host of hitchhikers to your aquarium. Small Copepods (essentially aquatic bugs that fish love), star fish, worms, sponges , corals, crabs, and even more exotic surprises... Not always good though. It's also usually covered in colorful coralline algae, the hard colorful (typically blue) crust that covers most things in a tropical reef.

    Heh. No wonder I never heard of it, I didn't have the guts to attempt saltwater tanks I never ran into the problems with undergravel filtration that you mentioned. maybe it was the way I cleaned my tank...

    It's perfectly fine for freshwater and even doable, albeit not advisable, for some salt water fish. Although its still a good idea to vacuum the deitrus out regularly. A lot of saltwater critters are just too susceptible to any nitrate readings to thrive with one though, even when at barely detectable levels - without the real pricey test kits.
