Iron fertilizer for vibrant color enhancement system care Extra iron for high-demand plants UV-resistant For stunning aquarium foliage Red or rapidly growing aquatic plants have an elevated need for iron. As a result, iron deficiency is frequently observed in densely planted and brightly lit aquariums. The presence of iron is essential for these plants to achieve their full color potential and thrive healthily. The innovative system fertilizer sera flore 2 ferro was specifically designed to address this issue. It supplies the necessary iron to the plants, thereby enhancing their color development. What sets the new iron fertilizer sera flore 2 ferro apart is its prolonged availability. Many aquariums utilize UV-C water clarifiers that can quickly degrade standard iron complexes. Consequently, iron becomes accessible to the plants only for a brief period. Not so with sera flore 2 ferro. The incorporation of specially chelated iron ensures its availability over several days. Additionally, sera flore 2 ferro is free from nitrate and phosphate and is safe for all invertebrates. Recommended dosage Administer 5 ml for every 5.3 US gal. (20 liters) once a week or as needed.

Plant care solution for aquariums with minimal fish Comprehensive care Includes NPK for essential nourishment Designed for aquatic plants The essential nutrients nitrogen, phosphorus, and potassium play a crucial role in promoting the healthy development of aquatic plants. In aquariums that house a lot of fish, these nutrients are typically abundant due to fish waste and leftover food. However, in plant-focused tanks with few or no animals, the supply of these macro nutrients can be lacking, leading to subpar plant growth. sera flore 4 plant has been specifically formulated to provide aquatic plants in aquascapes and Dutch-style setups with nitrogen, phosphorus, and potassium in the ideal proportions – ensuring vibrant and robust plant growth. It is safe for all invertebrates. Suggested dosage:  1 – 5 ml of flore 4 plant (based on plant density) for every 5.3 US gal. (20 liters) of aquarium water each day or as needed.  

Iron fertilizer for vibrant color enhancement system maintenance Extra iron for high-demand plants UV-resistant For stunning aquarium flora Fast-growing or red aquatic plants have a particularly elevated iron requirement. As a result, iron deficiency often arises in densely planted and brightly lit aquariums. However, these plants need iron to showcase their full color potential and maintain healthy growth. The innovative system fertilizer sera flore 2 ferro has been specifically designed for this scenario. It delivers ample iron to the plants, fostering color enhancement. What sets the new iron fertilizer sera flore 2 ferro apart is its prolonged availability. Many aquariums utilize UV-C water clarifiers, which can quickly harm regular iron complexes. Consequently, the iron remains accessible to plants for only a brief period. In contrast, sera flore 2 ferro employs specially chelated iron that guarantees long-term availability over several days. Additionally, sera flore 2 ferro is free from nitrate and phosphate, making it safe for all invertebrates. Recommended dosage: Use 5 ml for every 5.3 US gal. (20 liters) once weekly or as needed.  

Plant care solution designed for aquariums with minimal aquatic life Comprehensive care Contains NPK for essential nutrition Ideal for aquarium vegetation The key nutrients nitrogen, phosphorus, and potassium are crucial for the thriving growth of aquatic plants. In aquariums populated with numerous fish, these nutrients are readily supplied through their waste and leftover food. However, in plant-focused tanks that have few or no animals, there can be a shortage of these vital macro nutrients, leading to stunted plant development. sera flore 4 plant is specially formulated to provide aquatic plants in aquascapes and Dutch-style tanks with nitrogen, phosphorus, and potassium in the perfect balance—ensuring robust and healthy growth. It is also safe for all invertebrate species. Suggested dosage: 1 – 5 ml flore 4 plant (based on plant density) for every 5.3 US gal. (20 liters) of aquarium water daily or as needed.

To boost disease resistance Comprehensive care Enriched with essential micronutrients, trace elements, and vitamins Designed for aquarium plants Many aquariums often lack crucial nutrients in adequate quantities. As a result, plants may struggle to grow, fail to exhibit their vibrant colors, or even become stunted. sera flore 3 vital effectively fills these critical nutritional gaps, ensuring a consistent supply of essential micronutrients and vitamins through daily application. The introduction of rare yet vital trace elements enhances the disease resistance of aquatic plants. Your plants will thrive and become less vulnerable to external factors. sera flore 3 vital is free from nitrates and phosphates, making it safe for all invertebrates. Recommended dosage Administer 5 ml for every 5.3 US gal. (20 liters) daily or as needed.

For strengthening disease resistance Systemic care With essential micro nutrients, trace elements and vitamins For aquarium plants Many aquariums are lacking vital substances in sufficient amounts. Plants are therefore limited in their growth, do not develop the desired colors or even become stunted. sera flore 3 vital reliably closes these dangerous supply gaps and allows a constant level of essential micro nutrients and vitamins by daily dosage. Disease resistance of the aquatic plants is enhanced by the addition of very rare, but important, trace elements. The plants will remain healthy and become less sensitive against external influences. sera flore 3 vital does not contain any nitrate nor phosphate. It is well tolerated by all invertebrates. Recommended dosage Dose 5 ml for every 5.3 US gal. (20 liters) daily or as required.
