well heres my little, go against the grain bit of anecdote.......Ive used nothing but H2Ocean for a year on this version of my tank(Ive actually used the salt for about three years straight all together)....the thing that draws me to this salt is the fact that it is a naturally evaporated salt, not a synthetic...I couldnt care less what the levels are because no salt is perfect.......they all lack something......That being said, I have not dosed a single one of the big three (Ca, Mg and DKH) in the whole year + the tank has been running.....I have no Idea what my parameters are, as I havnt tested the tank either.......those of you that have seen pics of my stuff or have seen my tank in person know that my corals arent suffering........for those that havnt seen it, its heavily SPS and zoa dominant.....Im not getting huge growth in this version of the tank....I didnt really want huge growth after the last version, so this doesnt bother me.....my corals color is good and thats all that matters to me.........go H2Ocean!!!
