King British Safe Water This product helps to maintain the health of the fish in your aquarium by neautralising the ammonia produced by organic waste. King British Safe Water aids in the development of the biological filter of the fish tank by introducing large numbers of beneficial bacteria into the tank, in order to convert the harmful ammonia into nitrate and thereby kick-starting the cycling process. King British Safe Water helps to produce clean, clear and healthy water and is suitable for use in both coldwater and tropical aquariums. King British Safe Water is ideally suited for when partially changing fish tank water, when starting a new aquarium and also to boost the filtration within the tank. Dosage: 1ml for every nine litres / two gallons of aquarium water Bottle contains 100ml
