Bülent, could you please explain why mg/L to ppm conversion makes a big difference with Mg?
I will try to explain with an example:
Salinity of FM Solution is 35 ppm/53,0 mS at 25 C. Based on this salinity at this temperature, magnesium reading is 1397 mg/L (see attached). 1397 mg /L is equal to 1361 ppm, i.e. 1397 / 1.02637 (at 25C) = 1361.1075. So, if you compare your Salifert test result of this solution you need to target 1361 ppm as opposed to 1397. A lot of folks complain that there is a big discrepancy between the test kit reading and the solution. When I raised this issue with Habib (CEO of Salifert) he advised me to apply the above calculation.
I hope this helps.
Bülent
