Looking great Abdullah.
I fly frequently to Saudi and would love to see this tank when its running.
One thing you can try before going through the hassle of getting water transported to you each time is to run your high TDS water through a couple of sediment filters, i would go with a 10 micron then a 1 micron and follow up with a ceramic 0.9 micron. If the reason for the very high TDS is just sediment that might drop your TDS to values your RODI can handle.
Problem with your current solution is that you'll need frequent refill as the RODI will only give you a ratio of 1 to 4 of clean to waste water!!!
If the sediment filters don't drop the TDS considerably then youll have no other solution than what you did.
Not sure if you already got your flow pumps but i was advised by Ecotech when setting up my tank (88x34x30 220x85x75) to use 4 MP 60s. I still think you can get away woth only 2 60s one on each side and then 2 MP40s on the back. But then looking at your tank placement that would most probably not work as your tank is visible from 3 sides. Also seeing you have the overflow on the 4th side then vortechs will probably not work well as you'll need to orient your pumps to avoid causing a sand storm or the rocks in front...
Believe sea swirls on the returns and maybe a closed loop if you can still fit it would work best with this setup.
Can you post some pictures of the sump design you went with?
You are welcome at any time Maroun
Thank you so much for your suggestion and I will give it a try, I will add couple of sediment filters, i would go with a 10 micron then a 1 micron and follow up with a ceramic 0.9 micron and then the water goes to my RODI Unit.

Regarding Display Water circulation
I already purchased Tunze Turbelle Stream TS48 Pump Kit - 4 x 6105 Pump + 7095 Multi Controller
The Turbelle stream pumps produce gentle current speeds at high flow rates of up to 13,000 liters (3,434 US gal.) per hour.
