Potassium sulfate dosing

[TruckerAquarist]

Is dosing potassium sulfate an adequate method to raise potassium in a reef aquarium?

If so what are the ratios to mix and make the solution?

sulfate isn't terrible, but potassium chloride is better since there is no chance of running the chloride significantly higher by raising K ~100ppm or so.

If you do not have it already, now foods/iherb sells food grade potassium chloride.

But as noted, suitably pure potassium sulfate is ok.
