## Overview

Seachem Flourish Potassium is a premium 500 mL liquid supplement delivering 50,000 mg/L potassium to support vigorous growth in freshwater planted aquariums. Free from phosphates and nitrates, it prevents nutrient imbalances and algae issues, making it an essential part of the Flourish product line for maintaining healthy, vibrant aquatic plants.

## Description

Sachem Flourish Potassium contains 50,000 mg/L of potassium suitable for the natural freshwater 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 and maintain the highest level of growth. Flourish Potassium is an integral component of Sachem's plant products and is recommended for use with the entire Flourish line as well as our Fluorite gravel. Contains no phosphate or nitrate.
