It does, indeed. The point can be made, however, that any mature and healthy reef aquarium ecosystem with a decent amount of live rock has lots bacteria and sponges in both the display tank and filtration areas (if they aren't regularly removed). Perhaps what set's Tyree's method apart is the sheer quantity of these organisms that can be cultivated in a dedicated cryptic zone and the resulting increase in coral nutrient sources (live/dead sponge cells, additional nitrates due to sponges harboring significant numbers of nitrifying bacteria, etc.).
