Thales, I like your thinking.
The thing is guys and gals, is that not all reefers maintain their parameters the same way.
Some, like Randy, use a salt mix low in calcium and magnesium and choose to boost it right off the bat. He changes like 1% daily of his water.
Other reefers who change water every 2 weeks, rely on the salt mix with elevated calcium and magnesium to offset the consumption between water changes. They often supplement small amounts of Ca++ and Mag to maintain their levels between water changes.
So you see, its all how you use the salt and what husbandry schedule you maintain that determines what brand salt mix is best for your tank. Everyone does it different.
I agree with this point. If you buy a salt mix that has consistently provided 420 ppm calcium and all of a sudden, it does not, then that, is the problem.
Randy has been using IO for years, if not forever.
How do you think he would feel if, all of a sudden, IO mixed to 250 ppm calcium and 800 magnesium.
I do not think he would be too happy.
Reef Crystals has been a fine salt, for a long time. They recently became the most used salt from a recent poll conducted here.
I'm sure AM is not taking this laying down.
As Thales pointed out, there have been a few bumps in the road with a few different salt mixes over the years.
This too shall pass.
