Potassium Mixture

[tackful]

I have mixed 10 tsp. of K2S04 in 500 ml of distilled water for a solution that will provide .57 ppm/ml in 25 gallons, according to Chuck's Calculator. Is this excessive? The bottle needs a great deal of shaking to get everything dissolved. Thanks

oh yeah that stuff takes some elbow grease to dissolve in a bottle. Even straight dosing into the tank takes a while to dissolve.
