All aquarium water is unique
Over time, an individual little ecosystem is created in all aquariums. This works through a close interplay of organic and chemical/physical factors. The latter include the water, the substances this contains and the temperature, for example. The organic factors, on the other hand, include all living beings such as plants, animals and microorganisms that live in the aquarium, as well as elements that are introduced into the aquarium, such as food or substrates.
