I have thought along those lines many times; using cheap clams or such for filtration. You would think there would be plenty in the water column for them to syphon out if you had a large reef and fed heavily.
Between macro algae and clams, or other filter feeders one could theorize that a tank could be possible without the use of a skimmer or atificial filtration. Good water movement and small critters to break down the bigger wastes would also be beneficial. Basically, a mature tank.
Are there any threads with people doing just that? Using animals, live rock, macros, etc... for filtration? I guess the ALL natural way? No skimmers, no water changes, no additions besides regular, nutrient-rich feedings.
Kinda out there, but it seems possible with the right balance of each.
