For really serious P04 problems, use Foz Down. That will bring it down guaranteed. Then use GFO to maintain.

You didn't mention nitrates (unless I missed it). That is also a problem with new (or old) live rock. You have to get rid of that, too with bio pellets or carbon dosing. Be sure to use MB7 or some other beneficial bacteria supplement, or you will end up with cyano.

If you read my journal about the early days of my tank, you can see how I did it. Like I said, though, knowing what I know now, could get it done much sooner.
