Hi all,
I am in reef hobby over 20 years. 8 years back with my wife and my two chield we move to our new house. I was time to me to shut down my 15year old previous tank (90x80x(h)52cm seen on picture under.

So it was time for a new project. On new house plan, the tank place was drawn and during house construction floor was consolidated, and a hole was let between 1st floor and basement....Yes technical room was planed in basement.
Dureing the first seven years i had no time and no budget for tank as i had all external house work (garden.....) done by myself. I made a lot of concrate, move à lot of ground, sand, rock....but even no time for reef tank. These time profit to project as i read a lot and mature project. After discovering 3 thread on RC (from Sweet Ride, V1...rotate, Yano), it was clear that i had to better define what i want to achieve....the project had to be design and take care with a final goal in mind, as Yano done it so perfectly. Iwagumi is for me to reef tank what bonsai art is for trees...

So the tank will be viewable from three sides, and will divide entrance from living room. To be manageable the tank display is fixed to 120G with a near and stand-up point of view to provide tank imersion. The whole spirit is more shallow with 50cn (22")glass heigh. Due the stand-up point of view. The wood stand heigh is set to 120cm (48"). Some project sketch :

This tank will be a pure (or quasi pure) SPS tank with Staghorn in the 1/3 rear area and a milli garden in the front 3 sides viewable 2/3 area. Milli is one of my favorit SPS. Except one to three yellow tank there will be non big nore high nimber of fish.
 
Equipement :

- 120G Display tank : 130x70(h)x50cm (51"x27.5"x(h)22") with Beananimal external overflow box draining water to basement sump

- 42G bsament sump : 100x40x40cm (39"x16"x16")

- Return Pump : ATK MP6055 (6000lph/1600gph : 5.5m/18ft head presure 75W)

- Skimmer : ATI Powercone 200 ISDC

- Water flow : 2x RW15 on oscillator and Arduino drive

- Lightning : 430W Diy custom multichip led ligth on industrial 43V/43A

- Diy wood stand and furniture
 
Basement

The basement needed a big hard work as there were no wall or tiles on floor. After done that i had my place to host sup and surround equipement as a point of water near the sump.

It's a DIY combination of 50w 30000k, custom multichanel lumia 5.2 type and "OCW" royal blue rebel ES and violet 3W led divide in 8x 53w modules mounted each on a 20*15*2.5cm heatsink with 140mm/100cfm low noise fan fan

I have some more work to do :
- plumbing between DT and sump
- finishing lightning (mounting and wiring)
- some electrical routing
- achieving rock scaping with all dead rock
- dividing sump and built siporax bucket

Well done! Looking forward to the final product. I like your light area on the ceiling, as well as the custom led.
 
Thank's all for kind words. I can't wait to finish all these building process. All that represent a whole amount of work (time and quantity) and and significant amount of budget even the unit is only 120g compared to those in "large tank tanks" section and after one year long work it is quite time to acheive the end to do reefkeeping and not just building stuff. It was just necessary as the project is so custom to that DIY was the way to my eyes.
