OK Now to finalize Plumbing and water circulation:
After I placed my sand be in the tank I put the two Seios in the top left hitting the water surface to avoid stirring the sandbed. I was amazed with the surface agitation I got, in addition to the return of the flow as water was going from the pumps from upper left hitting the upper right and going down causing a powerful circular motion in the tank. I realize this will decrease when I have the rock structure and the corals in, however I'm considering keeping those pumps in the left upper side of the tank with one of them hitting the surface and the second going straight in the upper third of hte tank or maybe directed on the upper corals if it does not cause more flow than I want.

Assembled a 5 nozzle output (didn't have to do it manifold style as the output from all nozzles was the same) also added one output yesterday as the flow out of them was a bit stronger than I wanted. Thes can be rotated up or down left or right so I can direct them toward specific corals or areas if needed.
these were supposed to be fed by the same pump (OR 3500) feeding my CL, but when I saw the flow I'm getting out of this pump and considered the 20-30% loss because of the SCWD plus additional tubing I decided to to get another pump for the SCWD, one that has a 1/2 inch output this way the loss because of the SCWD is reduced. So I ended geting this pump:
It sits with the OR in the pump partition and I even have space for an additional pump or two in the future.
Basically this pump will feed the 5 outlets return line on the front of hte tank in addition to the SCWD that will go into one 3/4 inch locline on the left upper and two 1/2 inch return from the upper corners of the right side of the tank. this will also lead to variable flow of those 5 outlets as there is a difference in pressure when water is going from the single locline or the two other exits on the end of the tank. if this doesn't happen and I see those outlets taking much more flow and decreasing the effect of the SCWD then I can simply add a watervalve on the tube of the outlets and control how much they get.
I'm planning to T the output of the 3500 and divide it in two lines along the front and back of the tank with 2 1/2 inch outlets on each side and an additional 2x 1/14inch locline on the end of each this way I have additional variable flow which I can easily change after the tank is fully runnning and i can beter assess the needs of different flow in it. all nozzles will be threaded in not glued so I can direct them differently in the future.
Here's the SCWD connections I believe that the restriction from the SCWD will push waterin the elbow to feed my 5 outlet bar if not then a water valve will be added.
This sketch represents the final setup for water flow Please inform me if you find any flows in it this was I can modify it before starting to assemble it.
Do you think I should modify the 3500 outlets to have water go in a single direction leading to some rotation of the water in the tank or just have them face each other to create some turbulence in the tank. Would you direct such powerful return towards corals or just rely on the overall motion it create in the tank and direct it on the glass or differently.
In the end I will have the following for waterflow:
-Ocean Runner 2500:Return from sump 675 GPH I assume 550 after head loss
- Ocean runner 3500:in Pumps partition feeding 4 1/2 outlets and two dual Loclines 950 GPH I assume around 900 after a minimal 25 inch head loss and some tubing
-New Jet 3000: In Pumps Partition feeding 5 outlet return and SCWD to 1 3/4 ' Locline and 2 half inch returns from opposite side of the tank. around 800 GPH I assume 600 after loss from tubing and SCWD
-2 Seio pumps: these I might keep in the tank if I can hide them to make them invisible doing 850 and 685 these will hit water surface or I might orient one on the middle of the tank where corals should require more flow. any advice on positioning is appreciated.
-Couple of pumps in the pump partition connected to spraybars behind the rocks doing around 500 GPH
In total I will have 2550 GPH 17 x tank volume per hour without the Seios or 27 x tank volume if I keep the Seios.
flow through the sump would be 3.5x tank volume which should match my current skimmers performance or leave me room to double that volume when I get my second skimmer.
Any advice if this is overkill for a Softies and LPS and minimal SPS for the mooment? or flow modification? would be appreciated.
