Is there really a different between salt mix for reef tank? Instant Ocean Salt Mix, Instant Ocean Reef Crystal and RS Coral Pro?
Edit: what do you use?

Read their content labels.
Oceanic is high in magnesium: can help a very established reef stay up with it.
Instant Ocean is lower: good for starting out
Some salts are for fish-only: they are lower in calcium and other minerals and cheaper than reef salts.
What defines " expert or long time"?
I'm a relative newbie too! (this would be year 30 with marine tanks)
What I have found is that even if you stick to the same brand there will be differences between batches. I test new batches to see where they are at and adjust from there.
I use primarily Instant Ocean and/or Reef Crystals but have, at one time or another, used pretty much every brand on the market and IME, they all have the same issues and should be checked after mixing.
To help with consistency I order 5 or 6 200g boxes at a time so that (hopefully) they come from the same batch and should therefore be similar in make up.
I like Instant Ocean's habit of packing 4 plastic bags in the same volume as the barrel. I'm more confident that at least what I dip up is not just the finest grained mineral in the lot, but likely the salt as it was mixed at the factory.
I can't speak for all brands. IO is the only one I know that gives you separate packets in the large volume purchase.
