How are you defining detritus, sufficient flow and activity?Actually bioturbation prevents suffocation.
And with sufficient flow and activity in the sandbed, excess detritus is effectively removed with particle filters.
Sure, a sandbed continually churned in a storm of flow with large sifters like snails, large worms, starfish, etc. may not accumulate anything, including small particulate aragonite, but show me a home aquarium that has that much flow and that many large sand sifters. They reality is we can't have that much flow in our captive systems and our sand becomes a trap for everything, both active and inert that does not make it to the mechanical filter. Moreover, with the amount of flow required to effectively keep all of that material from accumulating, the aragonite would also pulverize itself. You are essentially talking about a fluidized bed!
Oddly, you stated above that we "over stir" our systems. You can't have it both ways
