Reef Crystal IO salt

[ponokareefer]

Finding a salt that is high in magnesium seems to be the most difficult task. I was using a high end salt, but the magnesium levels were still only in the 1100's, so I'm switching to Instant Ocean, which is half the cost, and just dosing magnesium. Don't be fooled by "independant" salt studies of the high end salt either, like I was. I'd contact littlesilvermax, as someone else has suggested, and get the magnesium in bulk to supplement for cheap.
