Sorry for not specifying the cooking the live rock concept Matt. LOL Like JIm, when i first read about it I though people were boiling or baking the rock. THis concept has been around for a while. Cooking the rock is like recharging the rock. It becomes bacteria oriented again by starving the algae to death that otherwhise inhibits bacteria from growing more densely. The way it is done is to take the algae's main source of nutrition away, which are phosphates and light. THe algae dies including the coraline but you do get detritus free rock and an awesome biological filter.
