Wavebox on back?

[monocus]

i have that set up in my 240.i made my overfow in an arc out of acrylic,with a stockman standpipe 3"away from my back wall and 3" away from my overflow(coast to coast).my wave box is siliconed to my overflow(top of wavebox at the bottom of my overflow combs)which i then surrounded with rockwork .it pushes the water at the middle to top of the tank and then the current returns it along the bottom of the sand
