Again, the numbers on the printed sheet included in the box aren't even in the same ball park as what I'm testing. Mag is still >1500. Cal is right at 500, and Alk 8.5.. All with a salinity right at 1.026 which is slightly higher than what the data sheet was measured at so I'd expect a little higher than stated in the box but certainly not off the charts.
I had the same, Mg 1550 & Ca 550 @35ppt - returned it
Mine was manufactured Aug 2016 - There's UK guys with manufacture dates right thru to Jan 2017 with the same issue
