Dosing for coral growth

[MitchM]

To give some idea of what a natural growth rate is (for a table acro, anyways), here is a link to a National Geographic article that shows a reef in the Phoenix islands.
This reef suffered a bleaching event in 2002 and the author went back in 2009 to find a table acro that had grown 4 feet in the 7 years since the bleaching event.
How many of us have 7 year old acros that are 4 feet across?

Given enough room, there are probably a few tanks out there that the corals could come close, so I don't think we are all that far from being fully successful raising corals.

Gives you an idea what type of growth you could be aiming for, anyways.

I've had several colonies that would put on an inch of growth in a month, so given the room and absence of fragging, I think we see similar growth in some tanks
