If you are going to be serious about growing corals, eventually you'll want the scrubber above the tank. As the live pods hit the water they will scurry for cover in the rocks, and the corals will sting and eat them.
But to start out with, and because you'll want to be looking into the scrubber every day for the first six month or so to see what's going on, keep it down low. Filtering will be the same, and the pumping will be easier. Then next year you can see if you still want to put it up high. Where you get the water from does not matter, so long as the pump inlet is near the waterline at the top, so that if a tubing leaks or breaks, only the top inch or so of tank water will be pumped on to the floor.
