John, the tower is a little over a foot and a half high.
99sf, would have probably taken me a whole day if I did it all at once. The right tower took about 3 hours, the wall in the left was like 2 hours and the left side took about 4-5 hours. I ended up using about 4 feet worth of rod.
Definitely good to have help in Jimmy on one day and my lady on the other. It'll probably be quicker for you because part of my problems were the huge mounds of rocks that were in the tank before aquascaping.
