TetraVital Promotes vitality, well-being and natural color splendor. TetraVital supplements vital vitamins, minerals and trace elements from the native biotope of fish that are missing in tap water or consumed in the aquarium. This creates a typical biological balance and creates a natural habitat for your fish and other aquarium inhabitants. Vitality and general well-being are enhanced by natural B vitamins and the trace element iodine (important in areas of iodine deficiency). The vitamin B complex contained in it also supports the growth of plants and microorganisms.
