Wavebox Freeboard Question

[TrailFish]

I am in the process of setting up a new tank with outside dimensions of 48 x 36 inches. There is an built in overflow that covers the entire length of the tank giving the main tank a 30" depth. I picked up a Wavebox I have yet to set up (still doing construction on the stand/walls/electric etc.) but I'm a little concerned about the recommended freeboard.

My question is whether the Wavebox will work in this configuration. I have only about 1" of freeboard above the overflow. I expected that any waves will cascade over the overflow as there we be no practical limit to the flow that the overflow can handle (I will have 2 x 1.5 inch drains to handle the the return water).

Does anyone have any experience with this kind of setup? Or will I just have to wait and see how things work out.

I am not sure what you mean by free board but one thing i know for sure that you will have a hard time tuning your wavebox because of the width of your tank. 36" is a bit too wide for 1 wavebox. You may need an extension...

What I meant by freeboard is the distance between the top of the overflow and the top of the tank (in this case the underside of the eurobracing).

The inside of the tank is actually 28" (just measured it) the rest is occupied by the over flow.

I think the wave will be 3/4" at most given the near cube shape of the tank. Very wide tanks need an extension to get more wave height.
