Seachem Flourish Potassium is a highly concentrated potassium (K) supplement formulated for freshwater planted aquariums. It supplies 50,000 mg/L of potassium, making it ideal for tanks with heavy plant loads, low K in tap or RO/DI water, or where potassium is rapidly consumed. As one of the three primary macronutrients (N-P-K), potassium plays a vital role in photosynthesis, protein synthesis, and enzyme activation, helping ensure robust plant growth and healthy leaf structure.

Key Features

  • Supplies essential potassium for freshwater aquatic plants
  • Ideal for fast-growing or potassium-hungry plants
  • Corrects yellowing, pinholes, or weak leaf structure
  • Highly concentrated: 50,000 mg/L potassium
  • Does not contain nitrogen or phosphorus
  • Safe for fish, shrimp, and snails

🧪 Usage Instructions

Initial Setup (Establishing potassium levels):

  • Shake well before use.
  • Dose 5 mL (1 capful) for every 125 L (30 US gallons).
  • This raises potassium by approximately 2 mg/L (ppm).

Maintenance Dosing (Regular use):

  • Dose 1–2 times per week, or as needed based on plant demand.
  • Use a potassium test kit if available, or monitor for signs of K deficiency (yellowing/pinholes in older leaves).
  • Use in combination with Flourish Nitrogen, Phosphorus, and Trace for balanced macronutrient dosing.

Frequently Asked Questions (FAQ)

Q: How do I know if my tank needs more potassium?
A:
Common signs include yellowing or transparent older leaves, pinholes, or leaf curling—especially in fast growers.

Q: Will Flourish Potassium cause algae?
A:
No, potassium does not directly promote algae. In fact, nutrient balance helps plants outcompete algae.

Q: Is it safe for shrimp and other invertebrates?
A:
Yes, Flourish Potassium is completely safe when used as directed.

Q: Can I use this in tanks with CO₂ injection?
A:
Absolutely. CO₂-injected tanks usually have higher nutrient demands, making K supplementation even more important.

Q: What’s the ideal potassium level in a planted tank?
A:
Target 10–30 ppm for optimal growth in medium to heavily planted aquariums.
