Great Stuff!

I am an especially obsessive person. Whether I wish to or not, I find myself demanding perfection. So, it is no small thing to say that this product is superior to all competitors that I researched. Indeed, I have never had a SeaChem product that has let me down. Their dedication to quality consistently surprises me. The salt is very fine - almost the texture of powdered sugar - which makes it dissolve almost instantly. It contains all of the trace elements that you need for your tank (note: use reef salt if you have a corals; use this Marine Salt for a fish-only tank). Also, I had to use several bags for my tank, and each bag was identical to the last. That uniformity is strangely missing from some other company's products. Honestly, you can't go wrong with this stuff.
