Tropical Sanital plus Ketapang is an aquarium salt with Ketapang leaves (Terminalia catappa) and oak bark extracts. Intended for conditioning of aquarium water for blackwater fish such as discus, angelfish, neon tetra etc., and brackish water fish. The addition of vitamin B1 alleviates stress, which is particularly important in case of numerous timid fish such as characins. Tannins and humic acids from the extracts of Ketapang and oak bark make the environment of the tank safe and healthy for the fish. The influence of these substances is particularly important in case of fish weakened by transportation, undergoing acclimatization period, or suffering from skin abrasions and injuries
