There are many ways to get your tank livestock ready, one way Is set tank up with LR and at a small piece of cured rock from a some what healthy pest free tank.
I always use Dry Rock it will take a bit longer but you don't have to be afraid for hitchhikers.
When I cycle a tank and that's the #2 with a formula, I use Dr Tim one and only but there others as well that do a good you.
Dr T will cycle your tank when follow directions in 5 days, after that you can ad one or two small fish, wait with corals as you will go through the second cycle process and that is Diatom algae.
After that clears up, and that varies by setup you can ad some easy corals.
So you got your tank, what equipment you going to run with it as Sump (maybe), lights, skimmer, water flow?
This can also help with your cycling process.
