Lol, you should have phrased your question better. You asked which salt in your opening. You didn't mention you were dosing and you mentioned basically by your question, "which salt is the best". Best for what specifically: growth, levels, tea tree oil? Lol
No one had their head up their *** and honestly, they were trying to help you with a "rookie" question as far as sps or any higher ended saltwater keeping is concerned. They then answered in a way that a rookie would understand. The error dude was in your line of asking..
If your looking for a salt suggestion, first, your going to get a million answers that will get you no where(because as someone mentioned, there's a million ways to skin the cat), and then, you need to be specific about what your looking for.
I would recommend KZ also btw, but I use coral pro for growth. It's pretty consistent from my experience. I am thinking about trying something new, but I haven't as of yet. I have used Oceanic and I can't remember what it was, but my sps didn't care for it to much.. I also used NeoMarine for a long time and it's levels were very good for dosing 3 part (brs). I used salinity which also was consistent. I used Tropic Marin long ago which was very consistent also.. So it's really a toss up..
But be more specific and less jumpy..
