## Long description

sera Florena is a liquid plant fertilizer in a 500 ml bottle, produced in Germany, formulated as a nutrient solution for aquarium and aquatic plants. It supplies essential macro- and micronutrients and specially stabilized iron complexes to support healthy leaf uptake and sustained growth in home and hobby aquaria. The formula contains no nitrate or phosphate and is designed to be well tolerated by invertebrates, making it suitable for planted tanks where balanced dosing is required.
Advantages
sera Florena delivers important minerals and trace elements in a liquid, easy-to-dose form that targets foliar nutrient uptake. The improved formulation includes UV-stable iron complexes that remain available even when UV-C clarification is used daily. Because the product contains no nitrates or phosphates it helps avoid excess nutrient loading of the water while preventing common nutrient deficiencies in aquatic plants.
Suitable for
Planted freshwater aquariums with plants that absorb nutrients through leaves
Community tanks containing invertebrates (shrimp, snails) where phosphate- and nitrate-free dosing is preferred
Hobby aquaria using UV-C clarifiers or when stable iron availability is needed
Routine liquid fertilization programs in home aquaria
Key specifications
Form: liquid nutrient solution
Volume: 500 ml bottle
Contains minerals and trace elements including stabilized iron complexes
Does not contain nitrate or phosphate
Compatibility: suitable for use in planted freshwater aquaria and safe for invertebrates
How to use
Shake well before use and dose according to the requirements of the aquarium plants and aquarium volume. Add the product directly to the aquarium water evenly distributed across the tank. Follow manufacturer dosing guidance for routine application frequency and adjust based on plant appearance and water test results. Combine with complementary plant care products if required to address specific nutrients not covered by this formula.
Usage recommendations
Use sera Florena as part of a regular fertilization schedule, monitor plant growth and water parameters, and avoid overdosing. For balanced plant nutrition, consider combining sera Florena with other sera plant care products when necessary to meet species-specific nutrient needs.
