Nutrition for aquarium plants Healthy plants prevent algae growth. Healthy plants prevent algae growth, supply oxygen, remove pollutants, offer hiding places and reduce pathogens. Healthy plants = healthy fish For the plants to flourish the the following demands have to be met: light as an energy source for CO2 photosynthesis, nutrients and trace elements as growth promoters. JBL fertilisers supply the plants with all main nutrients and essential trace elements. This way the plants can absorb all the required nutrients they need over the leaves and roots, and deficiency symptoms (e.g. iron deficiency) are thus prevented.
