Any of the well known salt mixes -- Tropic Marin, Reef Crystals, Red Sea, NeoMarine, ESV, etc. etc. - will work just fine.
Just find one that A) fits your budget and B) is has the Alk, Ca, and Mg parameters you'd like to run for your tank and run with it.
For example, I have some alveopora in one of my tanks and it's one of my favorite corals. It doesn't like it when the alk gets above 9 and is happiest when it's between 6-8. So, while I've used other salts without a problem in the past, I chose Tropic Marin because mixes up between 7-8.
