Flourish Potassium is a potassium supplement for planted aquariums that is highly concentrated (50,000 mg/L) and does not contain phosphate or nitrate. This makes it ideal for use with Flourish Nitrogen and Flourish Phosphorus. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium, and can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases, use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.

Seachem Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases, potassium could become the limiting factor to growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.
Why It's Different
The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either 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.
Directions
Use 1 capful (5 mL) for every 125 L (30 gallons*). This dose raises potassium by 2 mg/L. Repeat 23 times per week or as needed (in response to signs of potassium deficiency in older leaves which include: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.
