Tetra's water care products quickly and reliably prepare aquarium water for fish and plants, whether you're setting up a new aquarium or maintaining an existing one. Depending on the application, water conditioners make tap water suitable for fish, while other care products stabilise water quality, reduce organic pollution and promote balance in the aquarium.

After water changes, when introducing new animals or when water values are abnormal, suitable water care products can play an important role in protecting mucous membranes, reducing stress and helping fish adapt more quickly to new conditions. Products can also be used to prevent algae and cloudiness, support biological processes, and solve specific problems (e.g. unwanted substances entering the water), depending on the stock, tank biology, and care goals.

In this category, you will find Tetra water care products for freshwater aquariums in various designs and sizes, which are ideal for routine tasks such as water changes, as well as for responding to specific situations. For optimal results, we recommend regularly checking water values and using care products as needed.
