I know this is a little off topic, but i don't understand how a small current in the water would inhibit the growth of the corals. I mean with the Conservationists using things like biorocks (http://www.biorock.net) to speed the growth of coral production.

To the OP, like its been previously stated maybe your corals were still adapting to your system. If there wasn't very much PE until recently that may have been a sign that they were still under some stress. I would probably just keep on top of your calcium and Alk. for a little bit before adding a bunch of things that may or may not help out your situation
