APT E Estimative Index Refill 1000ml – Complete EI Method Fertilizer for High-Tech Planted Aquariums
APT E Estimative Index Refill 1000ml is the refill version of the powerful liquid fertilizer designed around the Estimative Index (EI) method created by Tom Barr. This nutrient-rich approach involves dosing generous amounts of macro and micronutrients to ensure plants always have more than enough to thrive—leading to faster, fuller growth and vibrant colors.
