Unlike tropical plant waters, mains water is lacking in a large number of nutrients. Many important plant nutrients and trace elements are absent or are removed from the water during treatment at waterworks. However, if just one nutrient is missing, plant growth stops and/or the plants perish (Liebig's Law of the Minimum). To be sure of healthy plant growth in the aquarium, the nutritional deficiencies in mains water must be compensated for and replenished to turn mains water into good aquarium water.
