  • Nutrition for aquarium plants
  • Healthy plants are important for every aquarium.
  • Plants supply the aquarium with vital oxygen for the aquarium dwellers, prevent algae growth and remove pollutants.
  • Healthy plants = healthy fish
  • Healthy plants prevent algae growth, supply oxygen, remove pollutants, provide hiding places and reduce pathogens.
  • For the plants to flourish the following demands need to be met:
  • Light as energy source for the photosynthesis of CO2, nutrients and trace elements as growth promoters.
  • With JBL fertilisers you supply the plants with all main nutrients and essential trace elements.
  • This way the plants get all the required nutrients they need to absorb over the leaves and roots to prevent deficiency symptoms (e.g. iron deficiency).
