Please note: This product has not been developed to deal with manual ammonia dosing or abnormal ammonia loading. It has been developed to break down the waste produced by aquatic life in Aquariums and ponds. If you are introducing high levels of ammonia into your tank then you are likely to experience spikes in water quality. An instant cycle of your tank is less likely to be achieved if additional ammonia is being introduced.
