Thanks a lot Eric!

Care to speculate why coral would concentrate iron into the skeleton? Has anyone studied for example the role of iron in Heliopora coerulea?

Usually a forum moderator posts a sticky thread if he's going to be away for more than a few days but I can't find one in the Eric's forum... :confused:
