About this product
MasterLine Potassium — Pure Potassium Liquid Fertilizer
Dial in your potassium levels with precision. MasterLine Potassium is a targeted liquid fertilizer based purely on Potassium (K), allowing you to raise K independently without introducing unwanted nitrates or phosphates into your aquarium.
Key Features
- Pure potassium (K) — no nitrates, phosphates, or other elements added
- Activates plant enzymes — potassium is essential for metabolic processes and overall plant health
- Precision supplementation — ideal for fine-tuning alongside other individual nutrients or all-in-one formulas
- Prevents deficiency — addresses yellowing leaf edges, holes in leaves, and poor growth
- 500ml — concentrated formula for long-lasting use
Whether you're running an Estimative Index or a custom dosing regime, MasterLine Potassium gives you clean, isolated control over one of the most critical plant macronutrients.
