Easily absorbable professional ferrous fertiliser for aquatic plants. Iron takes part in a variety of metabolic processes and, above all, plays an important role in the synthesis of chlorophyll - the green pigment. Its presence conditions the efficiency of photosynthesis. Iron uptake depends on macronutrient and micronutrient content, as well as pH and iron itself. A common problem in aquaria is iron deficiency because its form may not be absorbed by plants. Iron deficiency leads to the disappearance of chlorophyll and consequently to the development of chlorosis manifested by yellowing and necrosis of the leaves. The optimum concentration of iron in aquarium water should be 0.1-1 mg/l. AF Iron Boost contains a concentrated dose of easily absorbable iron chelate Fe2+ for aquarium plants.

1 ml AF Iron Boost per 100 l water once a week. Fertiliser application should be continued until satisfactory results are obtained. Recommended to be used in parallel with AF Micro and AF Macro. Absorbents such as zeolite and/or carbon may reduce the effectiveness of the formula. For aquatic purposes only. Protect from sunlight. Keep at room temperature in a tightly closed container, keep out of reach of children.

1 ml in 10 l of aquarium water will increase levels:

Fe Iron 0.38 mg / l (ppm)
