Aquaforest AF MACRO 250ml

Aquaforest AF Macro 250ml is a professional freshwater planted aquarium macro nutrient fertiliser designed to support fast, healthy and balanced aquatic plant growth. Formulated with essential macro elements including nitrogen, phosphorus, potassium and magnesium, this concentrated liquid fertiliser helps provide the key nutrients aquatic plants need for strong stems, healthy leaves, natural colour and long-term vitality.

Macro nutrients are required by aquarium plants in larger amounts than trace elements, especially in high-light aquascapes, CO2-fertilised tanks and heavily planted aquariums. Aquaforest AF Macro is particularly useful in planted tanks with a small fish population, where natural nutrient input from fish waste and feeding may not be enough to meet plant demand.

Key Features

  • Professional macro nutrient fertiliser for freshwater planted aquariums
  • Supplies nitrogen, phosphorus, potassium and magnesium
  • Supports healthy growth, strong stems and natural plant colouration
  • Helps prevent macro nutrient deficiency in aquatic plants
  • Useful in heavily planted aquariums with low fish stock
  • Ideal for aquascapes, high-light tanks and CO2-fertilised systems
  • Supports cell structure, protein development, enzymes and plant energy processes
  • Recommended for use alongside AF Micro and AF Carbon Boost
  • Concentrated liquid formula for accurate dosing
  • 250ml bottle, ideal for regular planted aquarium fertilisation

Product Overview

Aquaforest AF Macro has been developed for freshwater aquarists who need a balanced macro nutrient supplement for planted aquariums. In a healthy planted tank, aquatic plants consume nitrogen, phosphorus, potassium and magnesium as they grow. When these nutrients become depleted, plants may slow down, lose colour, weaken or show visible deficiency symptoms.

This liquid fertiliser provides a convenient way to replenish essential macro elements in a controlled and consistent manner. It is especially useful in aquariums where plant growth is strong but fish stocking is light, as these systems often do not naturally produce enough nutrients to support demanding aquatic plants.

Benefits for Planted Aquariums

Aquaforest AF Macro helps support strong aquatic plant growth by providing the major nutrients plants need for structure, energy movement and development. Nitrogen supports leaf growth and green colouration, phosphorus supports energy transfer and healthy development, potassium supports nutrient transport and plant strength, while magnesium plays an important role in chlorophyll and plant vitality.

When macro elements are deficient, plants may show growth inhibition, weakened shoots, discolouration, yellowing, poor leaf development or reduced overall condition. Regular use of AF Macro helps maintain a more complete nutrient profile, supporting healthier, more attractive planted aquariums.

Suitable For

Aquaforest AF Macro 250ml is suitable for:

  • Freshwater planted aquariums
  • Aquascaped tanks
  • High-light planted systems
  • CO2-fertilised aquariums
  • Heavily planted aquariums
  • Aquariums with low fish stock
  • Fast-growing stem plant layouts
  • Tanks showing signs of macro nutrient deficiency
  • Aquarists using a complete fertilising routine
  • Planted tanks requiring balanced NPK and magnesium supplementation

This product is designed for freshwater planted aquarium use and should be dosed according to plant demand, aquarium volume and overall fertilising routine.

How to Use

Shake well before use.

Dose Aquaforest AF Macro directly into the aquarium in an area of good water movement. Use twice per week as part of a balanced planted aquarium fertilising routine.

Aquaforest recommends using AF Macro alongside AF Micro and AF Carbon Boost for a more complete plant care programme. If the aquarium has a higher demand for a specific macro nutrient, AF N Boost, AF PO4 Boost or AF K Boost can be used additionally to fine-tune individual nutrient levels.

Dosing Advice

Recommended dosage: 5ml per 100 litres of aquarium water twice per week.

For reference, 1ml in 10 litres of aquarium water raises nutrient levels by approximately:

  • Nitrogen: 5mg/l
  • Phosphorus: 0.35mg/l
  • Potassium: 2.5mg/l
  • Magnesium: 1.2mg/l

Do not use at the same time as other macro nutrient formulas unless you are deliberately managing a measured fertilising routine, as overexposure can lead to excessive plant growth and algae bloom.

Absorbent filter media such as zeolite and activated carbon may reduce the effectiveness of the formula, so consider limiting these media when using targeted plant fertilisers.

When to Use

Aquaforest AF Macro is useful when:

  • Aquatic plants need regular macro nutrient supplementation
  • Plant growth slows despite good lighting and CO2
  • Shoots become weak or growth appears stunted
  • Leaves show discolouration linked to nutrient deficiency
  • Running a heavily planted aquarium with low fish stock
  • Maintaining high-light or CO2-injected aquascapes
  • Using AF Micro and AF Carbon Boost as part of a full fertilising routine
  • Balancing nitrogen, phosphorus, potassium and magnesium in planted tanks

Storage

Store in a cool, dry place away from direct sunlight.

Keep at room temperature in a tightly closed container. Keep out of reach of children. This product is intended for aquarium use only and is not suitable for consumption.
