Dosing - can't find the right levels.

If your inhabitants are too concerned about it, I don't think you should be either. Honestly, I think there is some testing or kit discrepancies. It takes a TON of Mg to go from 1300-1900 Mg. To give you an idea I use about 1 cup of Mg mix to go up by 100 ppm on my 90 gallon tank.

I have had no issues using Salifert for Mg (I use Elos for Cal and Alk). I haven't used the Elos kit for Mg.

You didn't say which salt you're using. Have you done any water changes in the time that you have been messing with the dosing?
