Everything to do with water care and water treatment in the aquarium shop


Clear, healthy water is the basis of a stable aquarium. Careful water treatment is essential for fish, shrimps and plants to thrive. Tap water often contains substances such as chlorine, heavy metals or excessive hardness levels, which can be harmful to aquarium inhabitants and aquatic plants. With targeted water care, you can create optimum living conditions and promote the biological balance in the aquarium.


Natural water treatment

Natural water treatment uses biological processes to stabilise the water. Special filter bacteria break down harmful substances such as ammonium and nitrite, while natural water conditioners add organic acids or humic substances that promote the well-being of the animals and improve the water quality in the long term.

Chemical water treatment

Chemical water treatment agents are used when a quick response is required - for example after a water change or in the event of increased levels of pollutants. These products neutralise chlorine, heavy metals or excess ammonia and immediately make the tap water suitable for fish.

Filter media for clean aquarium water

An effective filter system is the heart of water care. Using high-quality filter media such as activated carbon, zeolite or biological ceramic tubes, the water is cleaned mechanically, chemically and biologically. This keeps it permanently clear, odourless and free of pollutants.
