geesh wish most of you actually tried this before giving positive or negative advise...
I have... and will give you some insight...
I have boiled and bleached live rock,
I used a stainless cooker for craw fish, and used 4 pool pucks of chlorine, I boild all the rock in the solution for 30 min, it will be white, as opposed to green, and will even cook off turf algae, at this point you will need to rinse the rock with hose, and then boil in clean water for another 15 min, repeat until you smell no more bleach.
you will need to full cycle the tank, will there be phosphates.. yes but not much, the new algae and bacteria will deplete this rapidly. the tank I run now is BB and had the rock bleached and boiled years ago, it takes a while but it will be live rock eventually.
