AquaForest AF Macro 250ml
AquaForest AF Macro is a highly concentrated, all-in-one macronutrient fertilizer designed to provide aquatic plants with the essential nutrients they need for intensive, healthy growth.
Its carefully balanced formula combines nitrogen, phosphorus and potassium (NPK) with magnesium, supplying key building blocks involved in plant cell structures, proteins, enzymes and nucleic acids.
Regular use helps support vigorous plant growth, strong shoots and intense, natural plant coloration. AF Macro is particularly well suited to heavily planted aquariums with relatively few fish, where natural nutrient production may not provide sufficient macronutrients for demanding plants.

Benefits
Complete Macronutrient Support
AF Macro provides four important plant nutrients — nitrogen, phosphorus, potassium and magnesium — in one concentrated formula.
Promotes Healthy Plant Growth
Macronutrients are essential for plant development. Regular supplementation helps provide the nutrients plants need to grow vigorously and develop healthy shoots and foliage.
Supports Natural Plant Colouration
A balanced supply of macronutrients helps maintain healthy plant development and supports strong, natural coloration.
Ideal for Heavily Planted Aquariums
Aquariums containing large amounts of aquatic plants can have a higher demand for nutrients. AF Macro is particularly useful in heavily planted setups with relatively low fish stocking.
Helps Prevent Nutrient Deficiency
Insufficient macronutrients can lead to slowed growth, weakened shoots and leaf discolouration. AF Macro helps replenish essential macronutrients and support healthy plant development.
How to Use
Dose 5 ml of AF Macro per 100 litres of aquarium water twice per week.
For best results, AquaForest recommends using AF Macro alongside AF Micro and AF Carbon Boost.
If your aquarium has a higher demand for a specific macronutrient, additional supplementation with AF N Boost, AF PO4 or AF K Boost may be used.
Dosage
Standard dosage:
5 ml per 100 litres of aquarium water, twice per week.
Nutrient Increase
1 ml in 10 litres of aquarium water raises approximately:
| Nutrient |
Increase |
| NO₃ Nitrogen |
5 mg/L (ppm) |
| P Phosphorus |
0.35 mg/L (ppm) |
| K Potassium |
2.5 mg/L (ppm) |
| Mg Magnesium |
1.2 mg/L (ppm) |
Important Information
Do not use AF Macro alongside other complete macronutrient fertilisers.
Combining multiple macronutrient formulas can lead to excessive nutrient concentrations, potentially resulting in plant overexposure and algae blooms.
If additional nutrients are required, use targeted supplements such as AF N Boost, AF PO4 or AF K Boost based on your aquarium's specific needs.
Also note that zeolite and/or activated carbon may reduce the effectiveness of the formula.
Ideal For
- Heavily planted freshwater aquariums
- Aquascaping setups
- Aquariums with a small amount of fish
- Aquariums with high plant nutrient demands
- Aquarists looking for an all-in-one NPK + magnesium fertilizer
- Use alongside AF Micro and AF Carbon Boost
Product Summary
Give your aquatic plants a complete foundation of essential macronutrients with AquaForest AF Macro. Its concentrated nitrogen, phosphorus, potassium and magnesium formula supports vigorous plant growth, healthy development and intense natural coloration.
Designed especially for heavily planted aquariums with low fish stocking, AF Macro provides the essential nutrients plants need when natural nutrient availability isn't enough to meet their demands.
