Sera florena is a complete iron fertiliser for aquarium plants, which is rich in nutrients and is characterised by its UV resistance.

Sera florena is a liquid iron fertiliser that contains important minerals and trace elements for the ideal growth of aquarium plants. A basic fertiliser that is particularly suitable for aquatic plants that prefer to absorb their nutrients through the foliage.

Plants in the ecosystem of an aquarium play an important role. They process pollutants from the water column and serve as an oxygen supplier through their photosynthetic activity. A full supply of important minerals and trace elements is necessary for healthy growth. Sera florena supports aquatic plants in their growth and ensures a vital and colourful appearance. Deficiency symptoms are history with the addition of this fertiliser and there are no excess nutrients.

The new improved recipe from Sera florena contains extremely stable complexing agents for iron, which keep the nutrients available to the aquatic plants for several days even when using a UV-C clarifier. This complete fertiliser is free of nitrate and phosphate and can be used without problems with invertebrates.

The combination of Sera florena and Sera florenette is particularly ideal. Both products are very well coordinated and thus supply all aquatic plants with all the necessary nutrients via roots and foliage.

Recommended dosage

Fertilisation should occur weekly with 5 ml in 20 l aquarium water or as required. The additional use of Sera florenette (substrate fertiliser tablets) provides the aquatic plants with nutrients via their leaves and roots.

Our expert Oliver Knott recommends:

A particularly UV-stable basic fertiliser for aquarium plants.
