I don't, however fyi, I have been using LiveAquaria salt since it came out 2 years ago, and my tank is doing very well on it. I even stopped dosing MG.
I live in Western Australia and we don't seem to have that brand of salt. There are some good value salts in the Eastern states but shipping costs are huge!
All I know is it being Chinese means it will never find a way into my tank. I find that not skimping on salt is crucial for your tank health. I use Tropic Marin Pro btw.
