Good read on Synthetic sea salts.

I found this browsing around trying to find solid comparisons of the many brands of synthetic sea salts it seems pretty legit and it involved some RC members as well.
Enjoy.

Only problem is the age of the study.

It is close to three years old but look at alot of the reading material on our hobby. It is possible that some of the manufacturers have tweaked their formulas a bit but this could be used for a guideline at the least.

Reef crystals have been tweaked since then, not sure about any others

Does anyone know if any salts have a guaranteed analysis and where to find them? Or even a run down of their claims other than our salt disolves faster than others?
