Yes, it's no different than any other system. You can use established live rock from someone else's system. I simply pulled a couple Bio-bricks from my established system. Pick some shrimp, hermits, and Snail to throw in the QT with the coral - this will help keep nutrients available to the corals.
I used Tropic Marin All For Reef for dosing a 1-part complete dosing system to keep things easy. I'm currently quarantining 30 SPS, a Trachy, some chalices, mushrooms, and zoas. These will cook for 76 days..... With the corals, I've got about 25 blue leg hermits, 12 Astrea snails, a Coral Banded Shrimp, and a filter feeding Sea Cucumber.....
I have a light, rock, powerhead, and that's it. 15 ml of TM All For Reef every morning. Everything is stable and happy.
