Dennerle Plant Care Pro Daily is a high-performance daily fertilizer for heaviliy planted aquaria. Aquarium plants require around 20 nutrients in addition to light and CO2 to grow healthy. If even one element is missing, the plants already begin to wither away. Nutrient deficiency manifests itself, for example, in weak growth, pale, yellow or glassy leaves (chloroses), dying leaf areas (necroses) or small, crippled leaves. Algae often begin to grow on weakened plants. The aquarium has a very special nutrient situation. Some nutrients bought in by the fish food are present in excess. Other nutrients are quickly consumed or lack completely.Dennerle Plant Care Pro Daily provides aquarium plants with all the vital nutrients and trace elements they need for powerful, lush growth. Thanks to biologically balanced combination of nutrients, all active ingredients are absorbed in approx. the same ratio. All nutrients and building substances are available in a directly usable, plant-active form.
