Yea I saw that, I will give it a check tomorrow. If the hloe ends up being too close I will cut an edge of the bulk head or remove the overflow and reinstall it (I have the left over silicone), In one week I can water test it to make sure it holds water, my stand is level on the side off my house and ready to go. I will fill the tank, insulate the sides and make a plywood condom around it, the top will be removable for refilling because of evaporation. What's cool is that the water test will be for four months, if there is a problem it will be easier to deal with it without fish and corals in it.
