Seachem Flourish Potassium is a highly concentrated supplement designed for hobbyists maintaining lush, planted freshwater aquariums who need a targeted approach to plant nutrition. By providing 50,000 mg/L of soluble potassium, it effectively resolves symptoms of deficiency like chlorosis and weak stems; however, users must measure doses carefully because it is a potent additive that lacks nitrogen and phosphorus, meaning it should be part of a balanced fertilization regimen.

Common indicators include yellowing of older leaves, small pinholes, or decaying leaf tissue.
Check for nitrogen or magnesium deficiencies, as these also cause yellowing. Ensure you are providing a balanced fertilizer in addition to potassium.
Ensure you are not overdosing the tank. Large, sudden changes in water chemistry can cause temporary biological imbalances.
To use this product, add one capful (5 mL) for every 125 liters (33 US gallons) of aquarium water. This dose increases potassium by 2 mg/L.
