## Long description

Liquid iron fertilizer for aquarium plants ZOOLEK Fe 100 ml supplies iron micronutrients in a concentrated liquid form designed for planted aquariums.

Advantages
ZOOLEK Fe is presented in a compact 100 ml bottle that allows precise dosing of liquid iron for aquarium plants. The liquid format ensures rapid dispersion and availability of iron to roots and shoots without introducing solid residues. When used according to the manufacturer’s instructions, the fertilizer helps to restore natural green hues and supports photosynthetic activity, reducing visible nutrient deficiency signs.
Suitable for
Planted freshwater aquariums with aquatic plants requiring supplemental iron.
Aquariums showing signs of iron deficiency such as chlorosis on new leaves.

Key specifications
Form: concentrated liquid iron solution suitable for aquarium use.
Volume: 100 ml bottle for multiple dosing cycles depending on aquarium size.
Active micronutrient: iron (Fe) provided in a plant-available chemical form.
Compatibility: formulated for freshwater planted setups; compatible with standard aquarium water parameters when used as directed.
How to use
Shake the bottle before use and dose the liquid iron into the aquarium water at locations with gentle circulation to promote even distribution. Follow the dosing frequency and amount indicated by the manufacturer for your aquarium volume and plant load. Monitor plants for improvement in leaf coloration over subsequent days and adjust dosing only as recommended to avoid excess iron accumulation.
Usage recommendations
Test water parameters regularly and combine iron dosing with a balanced fertilization routine that covers macronutrients and other micronutrients. Avoid overdosing; observe plants and consider lowering dosage if brown spots or algae increase, as those can indicate nutrient imbalances.
