AF PO4 Boost A precision phosphate supplement designed for freshwater planted aquariums. Phosphorus, in the form of phosphate (PO₄³⁻), is a key macronutrient required for energy transfer, nucleic acid production, and overall plant metabolism. Deficiencies can result in slow growth, dark or discoloured leaves, and poor root development. AF PO₄ Boost delivers phosphate in a highly bio‑available form, helping maintain optimal levels in your aquarium and ensuring aquatic plants thrive. It complements other nutrient supplements to support balanced, vigorous, and visually striking aquascapes. Key Benefits: Supplies readily absorbable phosphate to meet plant nutritional requirements. Promotes strong growth, vibrant foliage, and healthy root systems. Works in synergy with other macro and micro nutrient supplements for balanced fertilisation. Ideal for heavily planted tanks and high‑tech CO₂ systems. Simple to dose and maintain, supporting stable and predictable growth. Usage Guide: Dose: 1 ml per 10 L of aquarium water to achieve standard phosphate supplementation. Adjust dosage according to plant density and measured phosphate levels. Best used alongside AF Micro, AF Macro, AF N Boost, and AF K Boost for complete nutrient coverage. Avoid use immediately after dosing absorbent media such as zeolite or activated carbon. Store in a cool, dark place in a tightly sealed container and keep out of reach of children. Phosphate is a critical but often overlooked element, and AF PO₄ Boost ensures it is delivered efficiently and safely. Whether maintaining a mature display or enhancing a new planted setup, this supplement provides reliable, high-quality phosphate for plants to reach their full potential.
