## Description

Seachem Flourish Potassium, 2 L / 67.6 fl. oz.

## Features

- CONCENTRATED: Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is vital when maintaining a vigorous level of growth in a planted aquarium.
- SUPPLEMENT: Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content.
- USE: Flourish Potassium is used to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.
- POTASSIUM: Flourish Potassium is derived from potassium sulfate, which allows the user to adjust potassium levels without affecting nitrogen or phosphorus.
- DIRECTIONS: Use 1 capful (5 mL) for every 125L (30 US 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.
