Hi keeper, been reading yout article series on natural filtration. I was especially interested in the DSB section (also read the shimek: "how sandbeds really work"). You stated that DSBs
"Should not be unduly disturbed by the aquarist or overly active, large sand-digging critters".
I would sure like the filtration benefits of a DSB, but a greater motivation to have a deeper sandbed is that i want to house a goby/pistol shrimp (1 goby/1 shrimp on 28"x20" area) combination, the pistol shrimp needing a deeper sandbed and some gravel to really be able to do his thing.
But does this then make for a "dangerous" sandbed? The various zones not having time to develop, pockets of coarser gravel maybe accumulating detritus, much of the microfauna being killed of? What kind of sandbed should I implement to make my pistol shrimp happy, all the while not jeopardizing my filtration, optimally still getting some filtration benefits out of the DSB?
