I didn't take the time to read thru this whole thread, but I can't actually believe someone would buy live rock for $5-$7 per lb then destroy it by baking or cooking it. I guess if money is no object it's fine.
In prthd's original thread about "cooking rock" (
https://www.livingreefs.com/cooking-rock-t30841.html) I explained what it really means. All the pests you talk about need 3 things to live. Water, food and light. If the method I explained was used, the rock would still be alive and the pests would be gone. All it takes is time.......but to each his own. ;)
