I agree with Myka,
I changed to Reefers Best salt about 4 months ago, I haven't seen anything different. Before that I was using Reef Crystals.
I have been having some issues with corals, not sure why, but things dying... Not saying it is the salt, as I was having this issue before changing, thus the reason I am trying Reefers Best. But I can say it hasn't fixed anything for me.
I will say that RB mixes nicer than RC, much cleaner and less residue on the bottom after making the water. So I guess it is a purer salt mixture.
