enough waterflow?
wont add any internal powerheads

I would opt strongly against the SCWD. They have a rather poor track record for longevity.....If you are looking for good flow, and alternative for you CL might be to head over to RC and do a search for VFD control pump. They are a 3 phase pump that can be ramped up and down something similar to a Tunze powerhead..... Again a good reference for this setup might be to check out by doing a search "VFD control questions" over on RC......
20x-50x flow rate is sufficient as Corey suggested.....

yes the 3 holes under the wavebox will be the outtakes for the CL
It would be a 700++ Gallon system

I like the setup/design of the system....External overflow I'm guessing???? I would recommend with the manifold system to do alot of tweaking and testing....You might have to change sizes of fittings and such at certain areas to get equal or even flow....You might find at the very end of the tank your not getting any push from the returns. Maybe simple valves installed at strategic places might be able to regulate and control flow. Your flow would be strongest on your outlets closest to the pump and drop off at the ends......

The closest thing I have for comparison. The Penn State tank (96x42x30 ~530gal) has the main return "T"ed off and goes into PVC nozzles at either side of the tank pointing down/out and length-wise of the tank. There are three other closed-loops. Two pump to 1" seaswirls in the front corners of the tank, and the third to PVC nozzles at the front of the tank pointed out/down/back. In addition to that there are two modded maxijets mounted on the overflow box blowing parallel to the back panel behind the rockwork. There is also a Tunze stream (not sure of the model) mounted in the back right corner.
So yes, a larger tank's flow can be provided without using a rediculous number of powerheads, but you have to be creative about it. You won't be able to completely remove powerheads from the tank though. IMO the best way to go about this is a return with nozzles pointed down along the top perimeter of the tank, a closed loop with nozzles hidden under the rockwork and powerheads at either end (Vortechs preferablly). Make use of seaswirls. Powerful uni-directional flow is not as nice medium intensity random flow.

That is a nice setup. If you can make it past the first few minutes it's a good video...http://www.podcast.tv/video-episodes/Tank%20Tour%20with%20Dr.%20Sanjay%20Joshi%20of%20the%20500%20Gallon%20Penn%20State%20Reef%20Tank%20-%20Part%20Two-11419099.html

was thinking about that and will split up the middle closed loop only at the end with only 2 outlets towards the sides of the tank blowing up and inwards as support of the allready 2 seperate outlets there.???

Looking back at the pics where are they bulkheads located to flood your CL pumps? At 119.50" I think you'll need more than 1 wavebox to get adequate flow....length wise....
IF a second wave box would be needed where would be the best place to set it up? Cross corner on the other side of the tank in length or just next to it at the opposite corner next to the overflow?
Can anyone else confirm that a second wavebox is needed with this size tank or would one do in support of the 3 CL?
