Tank is coming along quite nicely. I'm curious how you're going about handling your Nitrates and Phosphates in the tank? I have a 600 on order and plan to add a reefmat like you did. Also, I was trying to tell from the pictures, but do you think there is additional room for a macro algae reactor in front of or behind the skimmer? I plan to load the tank really heavy and run mixed sps/zoas.
