Tetra AquaSafe will be refreshed with an anti-stress formula to better support fish health and wellbeing, especially during water changes. Tetras AquaSafe, which quickly and effectively makes tap water safe for fish by neutralising harmful substances such as chlorine, chloramine, lead zinc and copper, has been optimised with vitamin B which significantly reduces stress. Whats more, the inclusion of iodine and magnesium helps to promote vitality and growth, while specially formulated nurturing plant extracts maintain healthy fins, skin, gills and mucous membranes. The water conditioner also encourages the settlement and bioactivity of all-important nitrifying bacteria in the aquarium. These micro-organisms play a key role in creating a biological balance and promoting the health of all aquarium creatures.
