sera florena is the ideal fertilizer for the care of all aquatic plants which assimilate their nutrients mainly through the leaves. Aquatic plants play a fundamental role in the aquarium, as they remove harmful substances and nutrients for algae from the water. In order for aquatic plants to perform this important task, sera florena supplies the plants with all the important minerals and trace elements they need for healthy growth and intense colors. In this way, problems of shortage are avoided, without however polluting the water with unnecessary overdoses. Furthermore, the new improved formula contains innovative particularly stable iron complexes, which remain available for several days even with the use of UV-C ray sterilizing lamps. This product is free of nitrates and phosphates. It is well tolerated by all invertebrates. The combination of sera florena and sera florenette is perfectly balanced and meets all the requirements of the most diverse aquatic plant species.
