Flourish Potassium

🧪 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.
