Thanks everyone for posting all great the ideas. When I built my first stand it was 18'' wide then when I put my 120 on it I put two 4X4's and two 2X4's on it and just extended the stand so I have 6 4X4's on my stand. so the bulk head fits in that grove. I will order the bulk head wrench, I could not used channel locks, the screwdriver should work. I like the idea of making my own wrench. What I did was go to Ace and got a reverse thread bulk head, I placed my durso stand on it put it in my overflow, hand tighten the nut backwards (lefty) and then when I put the other fittings on the bottom I just tighten them (righty) and it tighten the nut to the bulk head Nice and tight but not overly tight. Thanks again everyone almost told m wife you should of let me buy the Elos so none of this would of happened. I guess I just wanted to live more.
