Ok, I put together the 250 mL. distilled water (thought I should try to do things right) and 14 1/2 tsp. Potassium Sulfate in a measuring cup. I made the dose 15 ppm - came out to 7 teaspoons and I only had a half-teaspoon measuring spoon.<br />
885 590 + 590/2 <br />
44250 885*50 &nb sp; <br />
6.91 7 tsp. K2SO4 <br />
Dose: 5ml (1tsp) <br />
15 ppm potassium <br />
I put 2.5 ml. in the tank tonight. The fish didn't like it so much. I'm a little surprised because there is still some K2SO4 not dissolved. I put it in the refrigerator.<br />
