Multi-ingredient mineral fertiliser with potassium for aquatic plants. Invaluable in tanks where potassium deficiency exists and during first few months when it is not recommended to provide other macro nutrients. Does not contain nitrogen and phosphorus, hence is applicable in aquaria with dense populations of fish in which these two elements are already available to excess as organic products of the biological breakdown of fish wastes. Such a composition reduces the risk of algae infestation and provides the plants with valuable nutrients which guarantee proper growth and beautiful coloration. Moreover, Aquaflorin Potassium provides potassium without raising the concentration of nitrogen and phosphorus, which is essential in tanks with aquatic plants.
