what went wrong

I think you have it! The large piece of coral I was using for base rock apparently can be the source of high phosphates. After removing the original Live rock, if I take out the remainder of that dead coral I will be left with only 20/25lbs of good LR which for a 55gallon aquarium will not be enough. Unfortunately living in Whistler I have no access to LR. Once the 72hrs of blocking any light should I just remove the reminder of the (dead coral) Base Rock? Will the 5 fish I have in the tank be OK? I will replace the LR I removed a month ago and use it as new base rock. Does this make sense?
