Flourish Potassium is a highly concentrated potassium supplement for the natural freshwater planted aquarium. 1 ml treats 10 gallons. Repeat 2-3 times a week, as needed. A 250 ml bottle raises the potassium level by 10 mg/l in 1,000 liters.

Use 1 capful (5 mL) for every 125 L (30 gallons*). This dose raises potassium by 2 mg/L. Repeat 2-3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.
|Soluble Potassium (K2O)
Derived from: Potassium Sulfate
Elemental potassium is present at a concentration of 50,000 ppm (e.g 5%). Fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientifically sound method of simple elemental equivalence.
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.
The most easily obtained sources of potassium 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.
Seachem's philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.
For over three decades, Seachem has been a company rooted in sound science. Their experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of their employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such hobbyist found the available solutions to aquarists' problems wanting. This resulted in Seachem's very first product: Cupraplex™ (today known as Cupramine™). Over thirty years later Seachem is still approaching old problems in a new way.
