Agreed, I get the temptation, and am interested in the anaerobic cycle reducing nitrates, but without ever changing water you're accumulating things mentioned above as well as salts, phosphates, hormones, other metabolic byproducts not reduced to ammonia, respiratory byproducts, dead skin/scale cells, even beneficial bacteria die off and get replaced, and their entire structure doesn't simply turn to ammonia.
