I've seen nice stand builds, where a smaller tank was put in the stand as part of the display. I've seen really nice refugiums as part of the display also. I'm thinking about doing something like this, for my frag/grow out tank. I was going to just put it inline in the basement, prior to the water fllowing to the sump. I could put one of the lines from my herbie/bean animal to the frag tank in the stand, which is drilled and would then go to the sump; and one to the sump. I would probably put this behind a door, or removeable panel. If I put the 40b under the stand with it's own light, I would not have to figure out how and where I'm going to incorporate the 40 into my basement sump area. Thoughts?
