Seachem Flourish Potassium – Potassium Supplement for Planted Aquariums

🌿 Promote Stronger, Healthier Plant Growth

Seachem Flourish Potassium is a concentrated potassium supplement designed specifically for planted aquariums. Potassium is one of the essential macronutrients required for vigorous aquatic plant growth and is often depleted in heavily planted tanks or aquariums using soft water. Unlike potassium nitrate or potassium phosphate, Flourish Potassium adds potassium without increasing nitrate or phosphate levels, making it ideal for precise nutrient management.

Key Benefits

✅ Supplies essential potassium for aquatic plants

✅ Helps prevent potassium deficiency

✅ Supports stronger stems and root development

✅ Promotes healthy green leaves and vibrant growth

✅ Contains no nitrate or phosphate

✅ Suitable for freshwater planted aquariums

✅ Safe for shrimp and freshwater invertebrates when used as directed

Signs of Potassium Deficiency

If your plants show any of the following symptoms, potassium may be lacking:

• Yellowing (chlorosis) in older leaves

• Brown or dead spots (necrosis)

• Pinholes in leaves

• Weak stems

• Poor root development

Why Choose Flourish Potassium?

Most potassium sources also add nitrogen or phosphorus, making it difficult to maintain the desired nutrient balance. Flourish Potassium is derived from potassium sulfate, allowing aquarists to increase potassium levels independently without affecting nitrate or phosphate concentrations.

Directions

Add 5 mL (1 capful) per 125 L (30 US gallons).

This dosage increases potassium by approximately 2 mg/L (ppm).

Dose 2–3 times weekly or as needed based on plant growth and deficiency symptoms.
