Why put on clean socks or clean underwear since you are going to dirty them anyways? Point being that people who are using dead rock (as well as live rock) should want to start with a clean system to avoid nutrient problems down the line. A piece of dead shrimp will add a little bit of nutrients to start a cycle but some dead rock can have all kinds of dead organics in it that could create nutrient problems in a system before the system has the biological capacity to handle the load. There can also be high levels of phosphates in dead rock and even live rock. Both the nutrients and phosphates can result in prolonged algae blooms and other issues that could be avoided by exporting what ever dead organics and nutrients are in the rock before putting the rock into a new system.
