Aqua ornaments are detailed figures made of durable polyresin paint, making them completely non-toxic. They do not affect the biological balance of the aquarium and are therefore suitable for both freshwater and saltwater aquariums. Items with LED are only suitable for freshwater. Before placing the aqua ornament in the tank, it should be rinsed with lukewarm water; no cleaning agents should be used. Particularly effective effects are achieved with a diffuser and membrane pump connection. The rising air bubbles not only create an idyllic atmosphere but also provide the water with additional oxygen.
