Off hand I dont know what size they are, but they are quite a bit longer than normal. Maybe six inches or so. I'll have to look at the specs sheet. The instructions said the pressure should be between 40 and 80 psi. Mines at 60 psi. I plumbed a valve/reducer into the input which I can control the flow with. I'm glad my house is plumbed in the plastic tubing vs the copper. It made it much easier to hook this thing up.

GE Merlin Tankless Reverse Osmosis System:
The Merlin Reverse Osmosis System is a new patented RO technology from GE that fits nicely under the kitchen sink or for light commercial applications.
The GE Merlin Reverse Osmosis System is a tankless RO system featuring on-demand, continuous-flow water production. There is no storage tank to fill. The reverse osmosis unit does not run until RO water is needed.
This GE Merlin reverse osmosis unit will provide clean, refreshing, and good tasting water for all drinking, cooking & ice needs.
The Merlin system includes a complete installation kit, designer air gap chrome long reach lead-free faucet, all interconnecting tubing, RO membrane, filters, fittings, drain connection, and installation instructions.
The GE Merlin Tankless RO unit operates on line pressure (40 psi required), which eliminates the need for an electrical pump in most applications. If needed, a GE Merlin Booster Pump is available here.
The GE Merlin patented high-production, low-energy membrane purifies between 720 to 1100 gallons of water per day depending on your water conditions. That is 50 times the output of typical home reverse osmosis products. The GE Merlin provides commercial water production at the price of a residential system. This high capacity performance creates new opportunities for light duty commercial applications.
The GE Merlin system is covered by a 3-year limited warranty for residential applications, and a 1-year limited warranty in commercial application.
Applications for the GE Merlin System: Home Use / Light Commercial, Restaurants, Coffee Shops, Juice bars, Ice Makers, Dentist Office, Aquariums, Grocery Misters
The GE Merlin high recovery system has consistent TDS rejection and membrane efficiency.
The GE Merlin RO System is engineered for the fewest number of connection points - less chance of leaks.
The GE Merlin reverse osmosis system's support leg also serves as a handy sump wrench.
The GE Merlin system works like a small commercial RO system. It uses two reverse osmosis membrane elements in series to produce the high flow of permeate. The concentrate from reverse osmosis element one is channeled into the inlet at the second RO element.
The GE Merlin stops the flow of water coming in when the system is not in use. An internal shut-off valve will close when the pressure in the permeate line reaches approximately 44% of the system inlet pressure. This function saves water by turning the unit off when permeate water is not being used. The inlet valve will open, and the GE Merlin will start making permeate water when pressure in the permeate line drops to approximately 11% of the system inlet pressure.
The GE Merlin has a 25% recovery rate. .

What does the TDS run coming out of the RO system?
I haven't measured with the TDS yet. I'll check tomorrow. It hooks up differently than any other r/o system I've had. I had to plumb it directly from the water lines, and placed a valve right after my splice to turn off the flow when its not in use. It has a 1/2 inch tube input vs the 1/4 inch on traditional systems. I plan to turn it on for 3 hours at a time to fill a 100 gallon tub for top off water and water changes. I may try a float valve in the future, but for now I will do it manually. It may be hard to find a solenoid with 1/2 inch inputs too. So far it's been pretty amazing. Goodwin9 would be the best person to attest to its performance.

Well today I visited the Local TSE. They had everything an aquarist would need in terms of plumbing and poly tanks. I picked up two 150 gallon 6 x 2 x 2 poly stock tanks. They barely fit in my FJ and were a struggle to fit down my stairs. I'm sure b/w the two there will be more than enough room to hold the live rock and sand.
I'm thinking I will most likely have to move my refugium and sand bed once the tank is down. In this case I will need these tubs as boilogic filters. I have to find a place to put them, then plumb them in case I need them.
Also here is a pic of my 3 tanks (125, 130, 72) ready to go and plumbed in-line.

Is the way you plumbed your 72 much better than plumbing through the bottom of the tank? I was thinking about that, but yours doesnt look bad at all.
The bottom of the tank is usually tempered glass, so drilling it is more difficult. You also have to have a hole in the stand for the plumbing to fit through. Otherwise though you could do it either way. Alot of people plumb the inputs through the bottom, to hide the plumbing, but there has to be a safety measure added so the tank doesn't drain on a power outtage. For the sake of ease, I put both the input and the returns at the top. I also have 2 returns for each input.
Ok I was able to break away from the visiting in-laws, so I went down and tested the water. I used two different TDS meters, both from the same manufacturer. One I had already and the other came with the unit and it says its factory calibrated. The tap water gave me a reading of 197ppm on one meter and 204ppm on the other. After running the Merlin for approx 5 min, they both read 001ppm. This is after running it through the resin filter post R/O unit. I'd say it's performing adequately. Thanks again Goodwin9.
