Seachem Flourish Potassium 500ml

Seachem Flourish Potassium supplies potassium in a form readily available to aquatic plants, addressing one of the most common nutrient deficiencies in planted tanks. Potassium deficiency typically manifests as pinholes in leaves and yellowing of older foliage. Each 5ml dose raises potassium by approximately 2 mg/L in 200L, allowing for precise dosing adjustments. Recommended dose is 5ml per 200L twice weekly, adjusted based on plant response and water testing. Safe for all fish and invertebrates.
