Well it is update time finally

I have gotten a fair amount done, though looking at the pics it may not look like it.
All the intank plumbing is done, painted and installed for the two dart closed loops. Each of these closed loops with have an ocean motions 4 way so there are a total of 2 intakes and 8 outputs. Each 2" intake was split into four 1.5" intakes with a manifold. This was all the 3000 gallons is not being drawn from one spot but spread out.
Paul for Oceans Motions gets credit for the overall water flow, he is a genius with water movement. The closed loop flow is going to be a rough "gyre" or dynamic flow which means the flow is all going in the same circular form and not being counter-productive. The flow will come down the back of the tank across the bottom to the front, up the front and across the top to the back. This is why there are four outputs along the back bottom (holes and plumbing redirected to accomodate this without drilling more holes) and four along the front top.

Plumbing was also done and routed to try and conceal as much as possible by the rockwork. The back of the tank will be black and the plumbing was all painted with black fusion paint (PVC sanded first to increase adhesion). I am very happy with the way this came out as the end product.
The background of the tank is going to bea mix of black acrylic and black paint. I wanted something to conceal the external overflow. So I added a piece of 1/8" black acrylic to the inside of the tank to hide this. There are then two large black panels on the outside of the tank in the lower corners. These are removable incase I need to inspect things back here (ie. sick fish, coral fell down etc). The rest (now clear in the below pic) will be painted black - basically around the holes in the back.
Covers in place:

In those pics you can also see the corian covered platform I have behind the tank. This came out very well. The darts will sit on here and be a platform to stand on to work on the tank. The holes in the platform are for the two drains to go down and through.
Also the baffles are all added to the sumps. I have not cleaned up the messy silicone yet in areas I made a mess but you will get the point. It is two 90 extra wides (36" x 30" x 18" - L x W x H) that will be plumbed end to end with four 2" bulkheads.
Sump that will hold the dual skimmers:
Second Sump - future plans unknown but it was needed for overflow of water in a power outage is the #1 purpose. It could house frags or something but no plans of this at this time:
Current front tank shot - most of the plumbing concealed, back panels on, the clear areas wil be painted black. The sea swirls on the top rear corners will be the returns from the sump:
