Iron Boost 250ml – liquid iron

Aquaforest AF Iron Boost is a liquid iron fertilizer for aquarium plants, aimed at keepers who see yellowing or pale leaves and need to correct iron deficiency. The 250 ml bottle contains an Fe2+ iron chelate that plants can take up directly, which helps prevent the chlorosis that follows when iron runs short.

Why it matters

• Form of iron: the product uses an Fe2+ chelate, a form the manufacturer describes as easily absorbed by aquarium plants, unlike iron forms that stay unavailable in the water.
• Dosing precision: 1 ml per 100 l of water raises iron by about 0.04 mg/l, so the dose can be calculated against the actual water volume.
• Target range: the optimal iron concentration given by the manufacturer is 0.1-1 mg/l, which gives a clear reference for checking whether supplementation is needed.
• Bacteria support: the manufacturer states that the product encourages the growth of nitrifying bacteria.

What it works with

The fertilizer is intended for planted freshwater aquaria where iron is the limiting nutrient. The manufacturer recommends using it alongside AF Micro and AF Macro, and advises that adsorbents such as zeolite and/or activated carbon may reduce its effectiveness, so they should be considered when planning filtration.
