AF Macro is a highly concentrated fertilizer that delivers a balanced blend of essential macro elements—nitrogen (N), phosphorus (P), potassium (K), and magnesium (Mg)—for intensive and healthy plant growth. Designed for heavily planted aquariums, AF Macro promotes fast growth, strong shoots, and vibrant natural coloration. Its carefully balanced formula ensures plants receive nutrients in the optimal ratio, supporting cell structure, protein and enzyme development, energy transport, and nucleic acid synthesis. Deficiencies in macro elements can lead to stunted growth, weak shoots, and leaf discoloration.
Supports Intensive Plant Growth: Provides all essential macronutrients for lush, healthy plants.
Enhances Coloration: Encourages natural, vivid plant colors.
Optimized Nutrient Ratio: Delivers N, P, K, and Mg in ideal proportions for aquarium plants.
Energy & Structure Support: Macro elements aid in cell development and energy accumulation.
Dosage: 5 ml per 100 L of water, twice weekly.
For best results, use alongside AF Micro and AF Carbon Boost.
Avoid combining with other macronutrient fertilizers to prevent overexposure and algae growth.
Absorbents like zeolite or carbon may reduce effectiveness.
For higher nutrient demand, additional supplementation with AF N Boost, AF PO4, or AF K Boost is possible.
Nitrogen (NO3): 5 mg/L per 1 ml/10 L
Phosphorus (P): 0.35 mg/L per 1 ml/10 L
Potassium (K): 2.5 mg/L per 1 ml/10 L
Magnesium (Mg): 1.2 mg/L per 1 ml/10 L
