Friendly Bacteria to Kick Start Your Filter.
A live culture of "friendly" bacteria for your filter. These bacteria help breakdown fish waste and prevent the build up of toxic ammonia and nitrite. Add to a new aquarium to help activate the filter, when adding new fish, after a filter clean/water change or after using a disease treatment. Suitable for tropical and cold water aquariums.
Always test your water using Aquarium Lab test kits.
