Waveboxes on peninsula tank?

[AMD30]

Hi, was wondering if i can use two waveboxes on the same end of my 120x48x24 peninsula tank? what types of adjustments to an overflow would be needed? i heard something about longer teeth in the overflow? trying to plan out the tank.
thx

Yes, you would use one wavebox and one wavebox extension to produce a wave, the tank is so long a double wave is possible and I would predict a double wave would be about 1" high. As long as you had at least 1.5" from the water surface to the top of the tank no modification should be required. Otherwise you will have to find a way to lower the water level.
