SEACHEM FLOURISH POTASSIUM 250ml – High-Concentration Potassium Supplement for Freshwater Aquarium Plants
Seachem Flourish Potassium 250ml is a high-potency liquid fertilizer delivering 40,000 mg/L of readily available potassium, formulated to meet the needs of rapidly growing aquatic plants in freshwater aquariums. Potassium is a vital macronutrient involved in photosynthesis, nutrient transport, and tissue formation, and is often depleted in tanks with low mineral content or vigorous plant growth.
Potassium deficiency can cause chlorosis (leaf yellowing), necrosis (dead, dry tissue), stunted growth, and weak root systems. Flourish Potassium addresses these issues by maintaining stable potassium levels, ensuring vibrant, healthy, and resilient aquatic plants. It is phosphate- and nitrate-free, making it safe for all aquarium inhabitants.
For best results, use alongside other Seachem fertilizers and combine with Seachem Equilibrium during water changes to stabilize mineral levels from the start.
