Thank you small fry. I really wantd to try something different with this tank.
Now I have finally uploaded pictures and will now explain the circulation that I posted earlier. Don't mind the brown
diatom bloom that is clearing up since my cycle ended.
This first photo is of the front of the tank showing the two jets loclined to the front and y-d off for one side of the Oceansmotions 2way:

O.K., here you see the two jets. The one aimed to the left, upper, middle corner is moving split water to the open left side of the tank around the glass to the other side and up towards the filtration. This can obviously be adapted to an overflow box in a different system. The right side jet is aimed towards the closed loop intake(next photo) and the right, upper, middle, corner moving water around the back of the tank at the same time the other jet is meeting it at the back middle of the tank pushing water over the shelf from the back. Great circulation from this single return. If I had a tank that was 3ft or longer, I would use an OM 4way and do two of these y-d off returns in a similar fashion.
The next photo shows the right jet aimed towards the closed loop intake and the back of the tank:

Here you can see the jet on the left aimed at the strained intake on the right. You can also see the mother bubble in the middle. Nothing too exciting but certainly effective.
The next and last photo is of the left side of the tank displaying the ultimate return(recent discovery and always future assembly):

O.K. here we go, this jet is a single return for the other side of the OM 2way. I happened to discover this on accident as I initially had the jet pointed towards the front of the tank(Paul from OM's original suggestion.)
What happened was the jet was so strong that it was swirling the sand revealing the bottom of the tank that many close loopers experience. So I made the decision to aim the jet more towards the corner of the tank to not stir up the sand. Now I still have the ability to create whatever type of wave I wish every 30 seconds. For example, if I aim it more towards the middle of the glass, I can make the wave come over the front of the tank instead of the rockscape. I can also aim it more towards the front glass to have some of the wave come to the back of the tank. Endless options. I will again say that if I was to set up a 4way OM on a longer tank I would do two of these returns off the back creating alternate waves from both front corners of the tank.
So there you have it, the most natural wavemaking system I have created to date. The jets are placed so that they will not directly flow onto any coral that is placed. Very effective, expensive, but worth it. After using a head pressure loss calculator this Blueline 40HD is moving 650gph out of 790gph by the way I have plumbed this close loop. When I get a video camera to use, I will try to get some video out to show this circulation. It is quite a site and honestly still gives me the chills
