Macro 2000ml – Macroelements

Aquaforest Macro is a liquid fertilizer that supplies nitrogen, phosphorus, potassium and magnesium, the macronutrients plants draw in the largest amounts. It suits planted freshwater tanks where the keeper wants a single, balanced base macro product instead of dosing each element separately.

Why it matters

• The formula combines N, P, K and Mg in a balanced ratio, covering the elements that build plant cell structures, proteins and enzymes.
• Dosing is set per water volume: 5 ml per 100 l, applied twice a week, which makes the amount easy to calculate for any tank size.
• The manufacturer recommends using it together with AF Micro, so trace elements are supplied alongside the macros.
• Deficiency typically shows as stunted growth, weak shoots and discoloration, while excess causes overgrowth, dark green leaves (with too much nitrogen) and fragile plants. Regular dosing within the recommended range helps avoid both.

What it works with

Macro is intended for planted freshwater aquariums that use CO2 and fertilization. It is designed to be dosed alongside AF Micro and should not be combined with other products containing macronutrients, because of the risk of over-fertilization and algae blooms. Zeolite and/or activated carbon may reduce its effectiveness. If a specific macronutrient is needed in higher amounts, the manufacturer lists AF N Boost, AF PO4 and AF K Boost as supplements.
