A bacteria starter seeds an aquarium with live nitrifying bacteria to establish biological filtration quickly and prevent New Tank Syndrome, the dangerous ammonia and nitrite spikes common in newly set-up tanks. The representative product here, Dr. Tim's One & Only Live Nitrifying Bacteria, contains live ammonia- and nitrite-oxidizing species and is dosed when setting up a new tank, after medication, or during large water changes. It is sulfur-free and odorless.
