Tetra brand calcium chloride safe? (bag pics inside)

[law086]

Hi folks,

I ran into this at a local hardware store and I was wondering if any of the chem guys can give me input on it's aquarium use. I seem to remember threads about Tetra brand stuff being OK.

People use it but it does mix up quite dirty. Reddish/brown sediment.

This product sheet shows the percentages of the contaminates found on the average basis in Tetra Flake. It looks pretty good to me, but I will let others pass judgement on this product.

FWIW, Tetra has other grades of calcium chloride which may better fit our uses in reef tanks:
