Salinity.
I like that it takes less volume of salt to reach my target ppt in a 5 gallon bucket, good solubility, and my sps are showing noticeable growth. No experimental design deployed, just anecdotal.
Yeah, it's a bit cloudy after a w/c but clears up within an hour or so. I don't bother to pre-dissolve hours before.
I also like the buckets/lids they come in... does that count?
