Dual wavebox placement

[Reeferhead]

Pennisula tank, 3 sides visable, 96 x 48 x 30, about 550 gallons. I'm thinking 2 waveboxes as my primary circulation. I want to put both on the same end as the overflow. Do the two waveboxes have to be right next to each other? Or can I put one on each side of the overflow? The overflow will stretch out to fill what ever space the waveboxes don't use on an entire 48" side.

Also, do you think the Waveboxes in combination with probably four enductor returns on a Oceans Motions will be enough circulation. I'll be keeping and mixed reef of mainly SPS, Zoas, and some LPS.

Finally do these things move sand much? I'm planning on a shallow sandbed.

They tend to form sand dunes overtime but that is about it. You can put one on each side of the overflow.

Hey Roger,

For a tank of 96"x48"x25", what would be the advantages or disadvantages of 2 waveboxes (at opposite ends) in inverse mode as opposed to 2 waveboxes next to each other in synchronous mode?

Thanks,

James

What would be the wave height be given my parameters?

Also, do the WBs need to be away from the sides of the tank for best results?

Finally, I've heard that if your overflow is too short the wave can crash over it and cancel itself out. If its too tall your overflow may not recieve enough water. How do one take all this into account and properly design an overflow to make best use of the wave boxes? I understand that its best to have the overflow in the center of the tank but I don't want to go that route.

Wave height depends on to many factors for me to give anything more than a guestimate and I have no first hand experience with tanks beyond 30" in width. My guess would be about 1".

Ideally they would be 1ft in from each end but there is some forgiveness in this.

Use an overflow that is short with durso pipes to make the water level nearly even with the tank- that will be your best bet.
