Do I need to add ammonia sulfate when mixing with hard water?

There's a reaction when mixing glysophate with hard water that stops it from working. Ammonia sulfate stops this reaction. Is grass out act similar to glysophate when mixing with hard water?

Answer:

The active ingredient in Grass Out Max, Clethodim, is not generally affected by hard water, so you should not need to use water additives. However, if the pH level of your water is higher than 7, then you may want to decrease the pH level for best results.
