Flourish Potassium

Flourish Potassium™ contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of the essential elements for maintaining vigorous growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the water source has low mineral content. In these cases, potassium could become the limiting factor for growth. Use Flourish Potassium™ to prevent potassium depletion (signs of which include yellowing of older leaves) and maintain the highest level of growth.

The easiest sources of potassium to obtain are potassium nitrate and potassium phosphate. Both of these sources add nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium™ is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.
