My macro just died!

[Millepora_Maniac]

HI Guys,
I had a book by Anthony Calfo, who is I guess some kind of reef Guru, and in there he warns about the nutrient levels getting too low and the macro algae going A sexual, at that point it realeases all of the nutrients that it has pulled from the water back into the tank at once. Which is not good considering many of us have used macroalgae for nutrient export. test your water for nitrates and phosphates and maybe do a nice water change to be sure. Good luck.
