Fin rot and fungal infections are among the most common diseases in aquarium fish. When you move fish, overcrowd your aquarium, or keep them with an aggressive one that chases them and nips at their fins, then your lovely fish becomes more prone to fin rot. Stressful, or bad aquarium water quality, can also cause fin rot and fungal infections. This can rapidly lead to secondary diseases, so it is necessary to cure these diseases immediately. The King British Fin Rot and Fungus Control is an effective medicine, which is ideally used to treat fin rot and fungal infections in aquarium fish.
Containing 2-Phenoxyethanol, this fin rot medicine helps stimulate the regeneration and healing of torn and tatty fins. These fish products also help promote tissue growth and can aid in the healing of bruised mouths and lifted scales. This fish fungal infection medicine is perfect for use in coldwater and tropical aquariums. You are recommended to read all the directions for use on the packaging before using this fungus treatment for fish.
One 100ml bottle of this aquarium fish fungus medicine can treat up to 900 litres of aquarium water. You must avoid contact with skin and eyes. You should wash your hands with soap and water after using this fin rot and fungus treatment. You are required to keep these fish supplies out of reach of pet and children. This product will stain if spilt, so be careful, and do not use it with other fish treatments or medicines.
