## Overview

Flourish Potassium is a highly concentrated (50,000 mg/L) potassium supplement designed specifically for planted aquariums. Its phosphate- and nitrate-free formula, derived from potassium sulfate, allows aquarists to boost potassium levels without affecting nitrogen or phosphorus, ensuring optimal plant growth and vibrant health. Ideal for preventing potassium depletion in fast-growing or low-mineral systems, it integrates seamlessly with other Seachem Flourish products to maintain a balanced, thriving aquatic ecosystem.

## Description

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 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.

## Features

- Potassium supplement for the planted aquarium
- Highly concentrated (50,000 mg/L)
