Product Information

Potassium is one of many vital elements that is naturally depleted in a busy aquarium. Seachem Flourish Potassium will replenish the levels and promote beautiful plant growth.

Watch out for yellowing or even dying plants, weakened stems and roots as signs of potassium deficiency. Flourish Potassium is derived from potassium sulphate, boosting the essential value so that plants can grow beautifully.

As the product is not made from potassium phosphate or potassium nitrate, it will not leach any algae causing elements into the water.

Dosage Instructions:

  • Use 5ml per 125 litres of aquarium water- this dose raises potassium by 2mg/l.
  • Dose 2-3 times per week as needed
