APT E Estimative Index 300ml – Complete Fertilizer for High-Demand Aquariums Based on the EI Method
APT E Estimative Index 300ml is a high-performance liquid fertilizer formulated according to the Estimative Index (EI) method created by Tom Barr. This approach emphasizes dosing generously to ensure plants always have more than enough nutrients, including nitrogen (N), phosphorus (P), potassium (K), iron (Fe), and essential trace elements.
The result is vibrant plant growth, intense leaf coloration, and strong overall plant health. Contrary to common concerns, abundant fertilization does not promote algae—instead, healthy plant growth competes with and suppresses algae naturally. Regular water changes are required as part of the EI method to reset nutrient levels and maintain balance.
APT E Estimative Index simplifies plant care by providing a complete nutrient solution without the need for additional supplements. It’s ideal for high-tech, heavily planted tanks with CO₂ injection and strong lighting, offering quick results and long-lasting value.
