Just a small update.. I decided on adding a cabinet over the top of the tank to keep the electronics and test equipment and I have the lights setup on flex arms. Now for something completely nuts but I have been throwing up the idea to add a 20gal custom sump/refugium. Now if I decide to do this then I will keep the divider wall and drill the bottom of the center section of the tank and install a Herbie style overflow, yes I know what your saying, "if you wanted to have a sump then why didnt you get the ext" I already have this one and this decision is still up in the air, I will know better on the next build.....
