Seachem Flourish Potassium™ – Targeted Potassium Supplement for Planted Aquariums

Unlock stronger, healthier plant growth with balanced nutrition. Seachem Flourish Potassium™ delivers essential potassium to support vibrant, resilient aquatic plants.

Key Benefits:

• Supplies essential potassium (K) for plant health
• Promotes strong, vigorous growth
• Helps prevent yellowing in older leaves
• Does not affect nitrogen or phosphorus levels
• Ideal for precise nutrient control

Potassium plays a vital role in plant metabolism and overall health. In fast-growing aquariums or soft/RO water systems, potassium can quickly become depleted — limiting plant growth and causing visible deficiencies.

Flourish Potassium™ provides potassium in the form of potassium sulfate, allowing plants to absorb it efficiently without altering other nutrient levels.

For best results, combine with:

• Flourish Nitrogen™ – nitrogen (N)
• Flourish Phosphorus™ – phosphorus (P)

✔ Together, they form a complete macro nutrient system

If you want strong, balanced, and healthy plant growth, Flourish Potassium™ is an essential part of your planted aquarium routine.
