I have used all of the above in my tank. I started out with IO because of the cost and I could get a 5gallon bucket. It worked well until I started adding more and more corals and I found that it was causing cyano outbreaks (or that's what I decided was causing them). I switched to Reef Crystals and didn't see much difference in how things were going. I've also used Red Sea but didn't like the cost of it. I went back to IO and was pleased for a while but those cyano outbreaks started up again. I am using (don't eveyone yell at me) Aquatic Gardens (petco brand) {Premium Marine Salt Mix. I've been using it for about 6 months now and I have exploded coral growth, clearer water and happier fish. I have no idea why it works so well for me but it does. It mixes very easily and my CA stays at 380-400. I have a lot of SPS corals and you can see the growth from week to week. It cost about the same as a bucket of IO and I haven't had a cyano problem since I switched to it. Go figure right?
