Most of my pails of IO have tested calcium 380 ppm, alkalinity 11 dKH, magnesium 1150 ppm for years. I went through 4 pails of H2Ocean and it was 400, 8, 1200. That's using Elos for calcium and alkalinity, Salifert for magnesium.

Thanks for the replies guys... I think I'll go see if the only pet store in town has any IO... likely the best chance of finding it.

For the lowest magnesium in salt I have used was ATI. I think it was around 600-700 . I don't see it available in most LFS though.
