Odin,
While I agree with your statement on cooking the rock I did it for a few reasons.
A: I already have a ton of live rock from my previous tank that has all of those organisms on it and will eventually transfer across to the cooked rock.
B: I have had great luck so far with no Aptasia or any other pests so this ensures that will continue.
C: I wanted Tonga rock to continue the look of the tank. I really like to look of the rock over the standard Fiji rock.
