Dr. Tank Potassium Fertilizer is a high-quality liquid potassium supplement specially formulated for freshwater planted aquariums. Potassium (K) is a vital macro-nutrient required for healthy plant growth, strong leaves, and proper nutrient absorption. Regular dosing helps prevent potassium deficiency, such as yellowing leaves, pinholes, and weak stems. This fertilizer is ideal for aquascaping tanks, nature aquariums, shrimp tanks, and community aquariums, ensuring lush, vibrant aquatic plant growth without harming fish or invertebrates. Potassium plays a critical role in enzyme activation, nutrient transport, and water balance in aquatic plants. Unlike nitrogen and phosphorus, potassium is not supplied sufficiently by fish waste, making regular supplementation essential for planted tanks.
