JBL ProFlora The 7 (+13) Balls Root Fertiliser Rejuvenate your aquatic plants directly at their roots with JBL ProFlora 7 (+13) Balls. Specially manufactured from high-grade clay, these nutrient-loaded root fertilizer spheres deliver targeted, long-term nutrition to heavy root-feeding species such as Echinodorus, Cryptocoryne, and Vallisneria. The specialized clay acts as a natural nutrient reservoir, absorbing excess minerals from the water and gradually releasing vital trace elements—like iron and essential minerals—directly to the plant roots over several months. Formulated without nitrates or phosphates, ProFlora Balls strengthen root systems and boost healthy plant growth without encouraging unwanted algae. Key Features: Targeted Root Feeding: Delivers essential nutrients and trace elements directly to plant root systems. Smart Clay Reservoir: Absorbs surplus nutrients and releases them slowly as plants require them. Algae-Safe Formula: Free of nitrates and phosphates to promote clean, healthy plant growth. Prevents Nutrient Deficiencies: Rich in iron and minerals to prevent yellowing leaves and weak stems. Easy Application: Simply push 1 to several balls into the substrate around plant roots as needed.
