When resting inside the DT, the flowtanks structure looks like this:
so with the eurobracing and all other components, the system looks like this:

I also use eggcrate to create the mechanical outlay of the rockscape
and I decided to add a three way wavebox at the end of the peninsula. It's removable in case I don't like it, but it adds another element of flow.

the large external circulation loop looks like this:
and here are the pipes alone to make it easier to understand

white pipes are drains from the DT to the sump.
red pipes are emergency overflows (into the sump in this case). green pipes are returns from the surge refugium (above the tank). There's another network that goes from the sump to the surge, but I'll cover that later. Finally, I add plywood doors to be able to access under the tank (storage) and to look inside the cavern region (usually dark). Here's the total design so far

Wow awesome planing mate!!!
I hope so bad that you will be able to set it up as soon as possible!!!

Thanks guys.
Ok - so a little philosophy about the tank. You might ask why I have almost half the tank in darkness and why the actual reef is an even smaller ratio of the total water volume. The sump, surge, ATS and other systems are probably another 500 gallons (better math soon). So.. why? I believe that natural reefs are composed of many zones and we're only interested in watching the pretty colorful sections. But the hidden sections are just as important as the visible sections. So I wanted to combine three zones in one tank: 1. The shallow bright reef 2. The deep dropoff reef 3. The dark cave reef This configuration achieves that. Next, these zones can easily create many dead zones and I'm personally a big fan of large gyre circulating flow. This is where the four windows come in. The two top windows and two bottom windows as well as the long direction separators in the vertical and horizontal directions really create 4 long paths and the powerheads in the back flowtank can be timed and driven to create circulating flow across any of the four flow zones. So - three light zones and four flow zones.

So there are 16 possible flow modes (really 14 since 0000 isn't a flow mode and 1111 can't really function since there'd be no sink to the sources.)
Here are the 6 normal modes and here are the 4 extreme modes and here the 4 gentle modes

So why the interest in the dark zone?
The eggcrate will only allow small fish to get in and out of this zone. So this will really be an inverterbrate and sponge zone. I expect this to become a breeding zone for shrimp, crab, etc... The difficulty is that this zone will not be accessible once the reef is set up. It can be flushed with water, but physical access will be limited. I don't plan any structures in this space - no rockwork or artificial structures like eggcrate, etc... (for now). There will be no sand intentionally in this zone, but I'm sure there will be some buildup. I'm considering bottom bulkheads to allow flushing this zone if needed. I might even use this as a the water change source.

This one will be in the design phase for a while. I'll run some small scale experiments but I not in a rush to spend the $$$ yet.
Measure three times, cut once.

ok. here's the filtration / external loop. This includes a sump, but only as a mechanical control interface to the surge/refugium. It really doesn't serve any other function - no media.
I would like to convert this to a settling tank, but that's not planned out yet. here's the front view: and the back view: Basically, there are four drain lines. The two ordinary drains operate like a conventional beananimal with one fully open and the second tuned to minimize bubbles under normal flow. The red line is the emergency drain. The difference here is a fourth drain line that has an actuated valve on it. This is timed to align with the surge events to try to control the bubbles. I employ baffles and a floating screen to reduce bubbles again. Then the pump stage. This has multiple pumps that push water up to the surge with minor taps to external loops. The pumps push water up using individual lines to get to an acceptable flow rate of 8-10K gph. There's no need for a siphon block because the pump outlets point up and all 5 are in a dedicated chamber. The outlet chamber floods into the refugium chamber and then a baffle to the surge chambers. Each has multiple actuated lines down to the tank and one has an emergency overflow to the surge. The pink are surge and the green are returns. Since they're all actuated, they can be repurposed to act as surges or controlled flow returns. The external lines lead out to the outside of the house - to the chiller, ATS and mangrove garden.

How fast is that surge going to be?
Wouldn't that put a lot of force / pressure on some of the tank walls?

The surge will be comparable to what I have in my current tank ~ 20 gal over 5 seconds per surge per event.
If multiple surges go off at the same time, it would be 80-100 gal / 5 seconds. This is a bit of a compromise in tank overhead and overflow capacity. It really doesn't exert that much force on tank walls in my experience. The force is buffered by the size of the tank. In my current setup, the surge is directed down the long path ~ 8 ft. By the time it reaches the far wall, it's already looped multiple times and created multi-flows.

So I'll start the self-criticism...
I have multiple flows into the tank - 4 controlled, 2 surge and two more lines I haven't shared yet. That's 8 inlets at 2" diameter each. The total will average about 10K gph or so. The surges will add bursts of flow of 20-100 gal over 5 seconds. How are 3 drains at 2" diameter going to manage that?? It's really 2 drains with one more dedicated for surge, but wouldn't that put the emergency overflow into constant use???

Rebuttal - the drains should be able to run in full siphon mode and 2" at 4ft should be able to pull 4K gph. Two of them can handle 8K and the last one can handle the surge allowing for a few inches of tank height to absorb the inrush.

Well here's hoping your ability to find the house that you want & built everything is just as good as your ability to make sketch drawings of what you want As this is something I hope I'm still alive to see happen

Criticism - but each of the 4 total drains have 6 or 8 ft of horizontal run. That would trap air bubbles and stop a full siphon from forming!
Rebuttal - but before the horizontal runs, they have a drop of 3ft. That should be able to form a solid siphon with enough pressure to blast out a large air bubble. Criticism - I think you need to work out the pressure drops in those angles to be sure. Also should add more drains to be safe. Rebuttal - There's no room for more drains. The circulation powerheads in the flowtank structure take up a lot of room and create an obstruction for more drains. Criticism - Look man! I'm just trying to help you out here... Ok - I'm not schizophrenic. I'm just thinking out loud to work out the bugs.

Well part of me says as long as you pay for round trip airfare... but then the sensible side of me says I grew up in this region, I'm acclimated to this weather which means I'm pretty much going to be a pansy if I go anywhere "out of season" which is most of the country during certain times of the year. I'm pretty sure Texas will only have a small window to where I'm comfortable doing anything (and unfortunately I'll probably be teaching during that window)
Besides I have been marveling at the engineering of our forefathers who used 2x4s to make a raised floor over a span of 12 feet (no wonder there's so much bounce to it) now let me put 350g of aquarium on it (translation: I'm busy with construction work for my own tank...)

ok - I'll settle for vetting out any bad ideas that might break the design.
with the goal of getting to something better and more robust, of course.

Thanks. I think there will be other needs to run wires and pipes to the outside so I'm thinking of having a rectangular channel 4" x 24" created under or in the concrete slab to allow for some flexibility. The problem is that I may need it to exit on two different sides of the sunroom... For example, I want the chiller in a cool shadowed spot but the greenhouse in a sunny spot.
I also don't know the conventional building tools to avoid this channel from getting flooded or filled with dirt (or critters - this is TX). Angled ends? Caps? My plan was to fill it with foam on all openings and then break up the foam and reapply if changes are needed. Every device would need a return too, but in this case, the mangroves and ATS share a return. Given the distance, this may need more to avoid a flood in case one return is clogged since it is open (unlike the chiller). Does it also need a booster pump? This part needs more thought but it's important.
