Aquaforest Macro is a balanced liquid fertilizer that supplies the four macronutrients planted aquarium plants draw in largest amounts: nitrogen, phosphorus, potassium and magnesium. It suits aquarists who run a planted tank and need a regular, measurable macro dose, and it is designed to be used together with AF Micro.
Why it matters
- Macronutrients are structural elements: they become part of cell structures, proteins and enzymes.
- They also take part in energy transfer and storage, and they are components of nucleic acids.
- A deficiency typically shows as stunted growth, weak shoots and discolored parts of the plant.
- Excess causes overgrowth, and with too much nitrogen leaves turn dark green while the plant becomes fragile and prone to damage.

What it works with
Macro is intended for planted freshwater aquariums, where it serves as the base macro supplement. Use it alongside AF Micro, and do not combine it with other preparations containing macronutrients, as this risks overfertilization and algae blooms. Zeolite and/or activated carbon can reduce its effectiveness. If a plant shows higher demand for a specific macronutrient, Aquaforest offers AF N Boost, AF PO4 and AF K Boost as additional supplements.

Frequently asked questions
The formula contains nitrogen, phosphorus, potassium and magnesium, the main building-block elements that plants use to form cells, proteins and enzymes. It is described as the basic fertilizer needed for healthy aquarium plant growth.
The recommended dose is 5 ml per 100 litres of water, applied twice a week. Dosing is calculated for the actual water volume in the tank.
Yes, the manufacturer recommends using it in parallel with AF Micro. Do not add other products that contain macronutrients at the same time, because this risks over-fertilizing plants and triggering algae blooms.
Yes, absorbents such as zeolite and/or carbon may reduce the effectiveness of the product. Keep this in mind if your filtration uses them.
A shortage usually shows as stunted growth, weak shoots and discoloured parts of plants. Too much causes excessive growth, and with too much nitrogen the leaves turn dark green, while the whole plant becomes weak and prone to damage.
