Seachem Flourish Potassium by by Seachem
Seachem Flourish Potassium provides concentrated potassium to support vigorous growth in aquariums with natural, living plants. This safe, effective supplement helps you avoid potassium depletion, yellowing leaves, and limited plant growth.
- Potassium supplement for the planted aquarium
- Helps maintain a vigorous level of plant growth
- Helps resolve yellowing, death/browning & weak stems & roots
Flourish Potassium contains 50,000 mg/L of potassium - one of the highest concentrations available. Water with low mineral content or systems with rapidly growing live plants can quickly deplete available potassium, causing potassium to become the limiting factor for further growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.
Potassium is most easily obtained from potassium nitrate and potassium phosphate, both of which add either nitrogen or phosphorus to the water and make it more difficult to maintain a specific NPK ratio. However, Flourish Potassium is derived from potassium sulfate, which lets you adjust potassium levels without affecting your tank's nitrogen or phosphorus.
Directions: 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).
