I suppose it just ceases to exist?

It's removed by siphoning, filter socks and your skimmer. If you just leave crud to rot in your tank like in a DSB nasty things happen. Better to keep your tank clean IMO. I keep 1/2" to 3/4" of sand in my tank and stir it regularly so nothing builds up. Tried the DSB thing but it didn't work for me. Much lower nitrates, and a cleaner tank after it was gone. Removing a DSB is one of the most disgusting things you'll ever do!
