🌿 Seachem Flourish Potassium – 250 mL

Seachem Flourish Potassium is a concentrated potassium supplement designed to prevent and correct potassium deficiency in freshwater planted aquariums. Potassium is a vital macronutrient required for photosynthesis, strong stems, and healthy leaf development, yet it is often depleted in aquariums through plant uptake and water changes.

This 250 mL bottle is ideal for small to medium planted tanks, supporting healthy growth without affecting nitrogen or phosphorus levels—making it safe and flexible for a wide range of planted setups.
