## Long description

Tropical Ferro-Aktiv 30 ml with iron is a concentrated liquid plant fertilizer formulated for freshwater aquariums. It supplies bioavailable iron to aquatic plants to prevent and correct iron deficiency, supporting natural green and red leaf coloration and steady growth. The compact 30 ml format is intended for regular dosing to maintain micronutrient balance in planted tanks without altering general water chemistry.
Advantages
The formulation provides iron in a plant-available form that is readily absorbed by aquatic plants, helping to avoid chlorosis and pale new leaves. As a liquid concentrate, it enables precise, repeatable dosing and integrates with routine aquarium maintenance. The product is designed for use in planted freshwater aquaria and is compatible with common fertilization schedules for maintaining stable micronutrient levels.
Suitable for
 Freshwater planted aquariums with live aquatic plants
 Aquaria showing early signs of iron deficiency such as pale or yellowing new leaves
 Maintenance dosing to sustain healthy leaf coloration and gradual plant growth
Key specifications
 Form: liquid concentrate
 Volume: 30 ml
 Active role: supplies bioavailable iron (micronutrient) for aquatic plants
 Intended water type: freshwater planted aquaria
 Use frequency: suitable for regular dosing as part of routine plant fertilization
How to use
Use Tropical Ferro-Aktiv as part of a regular fertilization routine for freshwater planted tanks. Shake the bottle before use. Dose the product according to aquarium volume and plant demand; add the measured amount directly into the aquarium water distributed across the tank to avoid local concentration peaks. Monitor plant appearance and adjust frequency or dose gradually if needed. Combine with a balanced macronutrient program to support overall plant growth.
Usage recommendations
Test and observe plant condition regularly: increase dosing if new leaves remain pale, reduce or pause if excess algae or signs of nutrient imbalance appear. Keep dosing consistent and store the product in a cool, dark place out of direct sunlight. Avoid overdosing by following recommended dosing intervals and measuring precisely.
