Tetra AquaSafe is a water conditioner for freshwater and saltwater aquariums, which neutralises harmful substances and processes tap water to suit fish.

All fish need environmental conditions appropriate to their needs in order not to get sick. We can only partially understand nature in an aquarium, but we can make it as pleasant as possible for the animals. The aquarium system works optimally if water, planting, devices and fish are coordinated. The water is particularly important. It should show parameters similar to those in the fish's habitat. The flourishing of microorganisms also depends directly on the water quality.

Tap water is generally the most suitable - but always with AquaSafe! There are differences between saltwater, drinking water and natural freshwater that you can taste and smell. The reason for this are factors such as organic and inorganic pollution, climatic influences and ingredients that affect water chemistry. Every body of water gets its own character. But there are also dangers in tap water. There are heavy metals from pipelines, such as copper, zinc and sometimes lead, in the water. The concentration of chlorine in drinking water for disinfection is harmless to humans, but dangerous for fish even in the smallest concentrations since it damages the gills. For this reason, water should be treated with Tetra AquaSafe in a way that is fish and plant-friendly when it is newly set up and every partial water change.

Tera AquaSafe reliably protects fish and plants from harmful substances in tap water and adds important vital substances for natural aquarium water. The optimised formula is ideally tailored to the care needs of your fish's skin and fins. The water conditioner immediately neutralises dangerous chlorine, chloramine, copper, zinc and lead. Fish's gills and mucous membranes are protected, B vitamins reduce stress. Tetra AquaSafe promotes vitality, growth and well-being through the addition of iodine and magnesium and ensures clear water by promoting the growth of useful bacteria.


Shake well before use. Add 5 ml of Tetra AquaSafe per 19 l of newly added tap water directly to the aquarium.


When setting up an aquarium, changing part water and transporting fish. Suitable for all freshwater and saltwater aquariums (switch off protein skimmer).


The blue colour disappears immediately after use!

Oliver Knott recommends:

With every new installation or partial water change, dangerous substances from tap water should be neutralised with Tetra AquaSafe!
