Liquid Aquarium Fertilizer for Planted Tanks, 250 ml Iron Micronutrient and Simple Pump Dosing

Give the plants in your aquarium a measured source of iron, a micronutrient involved in chlorophyll production and the way plants use light. This 250 ml liquid fertilizer fits naturally into a careful planted-tank routine.

Small doses matter with this concentrated micronutrient. The pump provides a convenient measuring reference, while the stated guidance offers starting amounts for 10-gallon and 55-gallon aquariums.

Key Features

• Iron is used in chlorophyll production, supporting an essential part of aquarium plant growth and light absorption.
• The fertilizer is intended to encourage darker reds and lusher greens, making it especially relevant when caring for colorful planted aquariums.
• Reddish plants are specifically noted as responsive to iron, giving aquascapers a focused supplement for red plant varieties.
• One pump measures about 4 ml, providing a practical reference when adding the small quantities this micronutrient requires.
• Starting guidance for two common tank sizes makes initial measurement easier while recognizing that every aquarium may respond differently.
