All salts will be fine but there are pros and cons in addition to price points to each of them. In short Reef Crystal has worked fine for me in a softie/LPS Reef. I now only use Instant Ocean (Orange bucket) for a fish only system. Providing more details on the type of system you plan on running will help members provide feedback (what type of reef; will you be adding trace elements, fish only system etc.) Being new to the hobby I suggest going with the option that works for your budget and that you can easily get a hold of. Keeping it simple is always best in my opinion.
