Jesse, nice work, I cant wait to see it once you have water in there, I do agree w Michael, in that you should add some kind of Actinics.
Smalls, your sump is a typical sump of us cornerer's cramed but efficient. I want to add a fuge & will eventually, I'll turn my frag section to a fuge, but not now, not yet.
Kelso unfortunately I have no info on ballast on a glass aquarium, but I can tell you tha if your going to have a sump in the basement you should have a good return pump. As far as your skimmer, look into the Aquaclear HOB Remoras, they are great, they are rated for up to 75 gallons, but they have one thats rated up to 120 & its not that much more, I had one & loved it!!
