sera Florena Plant Fertilizer 250 ml Germany

sera Florena Plant Fertilizer 250 ml Germany is a liquid care product formulated for aquatic plants that absorb nutrients primarily through their leaves. Produced in Germany, this 250 ml bottle supplies essential minerals and trace elements that support healthy, colorful growth of aquarium plants while avoiding nutrient overload in the water. The improved formula contains stable iron complexes that remain available even when UV-C clarifiers are used during daytime. The product contains no nitrate or phosphate and is well tolerated by invertebrates. Used together with sera Florenette, it provides a balanced nutrient profile suitable for a wide range of aquatic plant species.

Advantages

sera Florena delivers essential micronutrients in a liquid, easy-to-dose form that targets foliar uptake of aquatic plants. The formulation avoids adding nitrate and phosphate to the water, reducing the risk of unwanted algae stimulation. UV-stable iron complexes maintain iron availability under UV-C treatment, and the product’s composition is compatible with invertebrates commonly kept in aquaria. The combination with complementary products enables a balanced nutrient regimen adapted to different plant needs.

Suitable for

• Freshwater aquariums with rooted and epiphytic aquatic plants
• Planted tanks where foliar nutrient supply is needed
• Setups that use UV-C clarifiers and require stable iron availability
• Aquaria containing invertebrates sensitive to nutrient spikes

Key specifications

• Form: liquid fertilizer for aquarium plants
• Volume: 250 ml
• Nutrient focus: minerals and trace elements including iron complexes
• Contains: no nitrate, no phosphate
• Stability: UV-stable iron complexes suitable for use with UV-C clarifiers

How to use

Shake the bottle before use and dose according to the manufacturer’s instructions for the aquarium volume and plant density. Apply the liquid directly to the aquarium water at the recommended intervals to maintain consistent micronutrient levels. Monitor plant appearance and water parameters regularly to adjust dosing if necessary. When combining with sera Florenette or other nutrient products, follow combined dosing guidance to avoid nutrient imbalance.

Usage recommendations

Use sera Florena as part of a regular care routine: maintain stable lighting, CO2 and water parameters, and dose the fertilizer consistently rather than in large occasional doses. When running UV-C clarifiers, continue standard dosing because the iron complexes remain available. Avoid overdosing and test water and plant condition periodically to ensure optimal growth and minimal algae risk.
