Exciting day. Jeff, great work. Even though we have spent over 2 years working on this design, we continue to tweek it during the installation phase. Jeff has come up we some novel approaches to water flow and distribution. Having the over flow box in the right corner was a very recent change. I love the idea. The tank will be viewed from the left, so one will have a very open view. Of course, the over flow box will be covered with live rock. I envision one or two islands to left of the tank, promoting the open view from some one looking at the tank from the left corner. As for the natural light, yes, I am concerned. I am hoping that my robust filtration system will keep the nutrients down to a level where the natural light will become an assest and not a detriment. We will see.
