Really "cooking" your rock means COMPLETE darkness for 3 months at least. The rock should end up looking like a..........rock. I mean regular rock, no coraline, just a very porous rock. The process forces the bacteria to feed off Phosphate and stuff that's in and on the rock, it's a way of "recharging", or "turbocharging" the rock. Problem is, the rock doesn't look as good until it's been back in the tank for a few months. You can use much less LR, if it's all cooked.
