Flourish PotassiumFlourish 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 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. Potassium supplement for the planted aquarium Highly concentrated (50,000 mg/L) Does not contain phosphate or nitrate making it ideal for use with Flourish Nitrogen and Flourish Phosphorus Seachem Treats - Gallons BFA Item # Flourish Potassium 250 mL 50 for 4-6 months SC04660 Flourish Potassium 500 mL 100 for 4-6 months SC04630 Flourish Potassium 2 L 400 for 4-6 months SC04680 DirectionsUse 1 capful (5 mL) for every 125 L (30 US gallons).
