API® ROOT TABS plant fertilizer promotes lush growth of aquarium plants with ingredients such as iron, potassium, and carbon that help develop strong roots and promote vibrant growth. Without proper fertilization, aquarium plants gradually yellow, drop their leaves, and die. API ROOT TABS plant fertilizer are formulated to supply key nutrients to help new aquatic plants grow and keep established plants flourishing. These nutrients are consumed over time in the aquarium, and must be replenished for plants to thrive. API ROOT TABS plant fertilizer are safe for use with tropical fish, and may be used in conjunction with a liquid fertilizer for optimal aquatic plant growth.
