changing the rockscape

Over the past 10 years or so I can only remember once when I rearranged the rocks in each of my tanks. And that was only because I figured I had packed them to close together and wanted to make caverns and runways. The only way that your tank is going to recycle is if your rock has excess die off and/or you replace more than approx 50 per cent of the water. In other words, you cause it to happen. If you are running mechanical filtration then any detrius that is stirred up will be trapped and you simply replace the medium. Personnaly, I wouldn't be rearranging the rock unless it was for circulation. Of course, a few pieces here or there in order to accomodate a new piece of coral will not hurt. IMO
