Ocean Pure Salt Mix

[Blue Ram]

I'm looking for some feedback from members who use this brand of salt. I purchased this brand on the recommendations of two local retailers who said it was "the best" and being a novice salt keeper, I relied on this recommendation. The issue I'm having is that my water is testing 10.6 for dKH (using Salifert test kit). I mixed up a new batch of replacement water (using RO) and adjusted to 1.024 sp. This too is testing at 10.6. I'm not aware of any other reason why the dKH would be so high other than the actual salt mix. Any advice and/or suggestions??
