Cupramine & Salifert Test Question

[dun2run]

I am dosing Cupramine and testing with Salifert. I just noticed that the dosing instructions on the Cupramine is read in mg/L. The Salifert test is in ppm. At full strength, should the test read 0.50 ppm? (Cupramine instructions say "Final copper concentration is 0.5 mg/L.)

Yes. ppm (parts per million) is the same as mg/L (milligrams per Litre).
