MonaLisa, thanks, post some pics of your tank as it progresses. I am keeping a bit of a journal on temps, nitrates, pH, salinity, S.G., Alk, Cal, and phos, just to plot trends and see how things go. I had a 55 reef 5 years ago but have been out of it since 01'. Things have changed a lot!! Hope to do better this time around. Good Luck on your tank as well.
