I used this salt (but it was hard to manage making the 2 part) and it was awesome. I moved to the Biosea (1 step down) for ease of use and had to ship it in from Aquarium Illusions in Edmonton. Still extremely happy with the salt. Tried a lot of others and found them lacking compared to this, especially IO which left crud at the bottom of every bucket.

Recently tried Reefer's best (when it was on sale at J&L) and found it to be about as good as Biosea but not quite as good as Marine Environment.

Hope that helps.
