Help with design for flow

The tank will be mainly SPS.

Since it will be a peninsula I would like to keep as few powerheads as possible or keep them well hidden.

Any ideas for the placement and size to make this a success?

It is not ideal as the waveheight will be shortened and the wave will alternately starve and then surge the overflow box creating noise. Ideally the overflow would be centered on a back wall. It could work but the problems will be what I mentioned here. You will still need some streams or a closed loop for circulation and the wavebox will require an extension for a tank of that size.
 
How does the extension work? Where would I add streams?

The tank has not been built yet. Do you have another suugestion for placement of the overflows/wavebox?
 
If you could center the overflow on the back wall and place the wavebox and extension where you planned that would be perfect. The extension is just a dummy wavebox, it just boosts the power, you need one after you pass 320gals. The Streams would go one on each side blowing down the length of the tank.
 
It is a paninsula tank so when you say back wall it is already on what would be considered the back wall. If you mean on the long wall that would put the overflow in the middle of one of the viewing areas. Is that my only option? I would really rather not have it in the viewing area. Also when I add the extension is it another box the same size? Does it go next to the current one? I need to make sure the overflows are planned properly so it fits.
 
The extension is the same size. I understand it is not ideal but if you keep the overflow on an end as you have them there will be a fair amount of splashing noise. In the middle the water level stays constant so it just works better, quiet and without shortening the wave. The wavebox and extension can be placed on either end or one on each end, they can be one in each corner or both centered.
 
What about the streams? one in each corner on the oposite end? Pointing towards the middle? Which model?

I has considered doing an island style return in the middle of the tank so it would not be against any wall. I could then pile rock up around that to try and hide it. WOuld that be a much better design then putting it on the one end?

One of trhe things that made me go away from putting it in the middle is it would then split the wave no?
 
No, the wavebox works on the principle of resonance frequency and it creates one wave, with the crest on one side, trough on the other, center is constant or the fulcrum point. If you place the wavebox and extension on the same side, one in each corner it should work fine. For Streams, if you use the wavebox 2 6100's should be sufficient, if you don't use the wavebox system 2 6200's would be the minimum.

Roger: what if you put a wavebox near the far end facing the other wavebox with some kind of brace coming up from the bottom of the tank?

as long as they face each other and are stable will they make a wave ??

I was think ing if that might work then some rock could be used to "hide" the box and 1 or two steams could be hidden there also to make sure the end gets good flow ??
one pointed into the end the other into the main area each at a different height.

or is this idea just not good ?

Not sure I follow what you mean?

crude sketch:

Eggs are streams, the two boxes with the "S" are the wave boxes.

the other two blocks are the overflows, the idea is to create a partial wall to let the wavebox fasten to and bounce waves from.

another idea: put the overflows in the center of the tank ??
like this:

then
the overflows and the wave makers are an island in the center.

just some ideas on how to try and make it work w/o losing a side of the tank.
 
Given the 10ft length I would put a 6100 on the overflow and one centered on the other side. Otherwise, yes, that is what I would suggest exept the overflow would be better off in the middle of the tank, the placement you show will work but with a splashing noise and shorter wave.
 
Do you mean only one on each end in the center or add another on to the center on each side?

If I put the overflow in the center like an island I could push water both ways then. Wave box and extension on one side and what then?
 
The water goes the same way no matter which side the wavebox is on. It creates one wave, one side crests the other troughs, the middle stays the same height. Yes, just one pump centered on each side.
