Dr. Tim's One and Only 120ml

Dr. Tim's One and Only is a live bacterial product developed by Dr. Timothy Hovanec, a pioneer in aquatic microbiology who was the first to identify the correct nitrifying bacteria species (Nitrospira, not Nitrobacter as previously believed) active in aquarium biofilters. This scientific pedigree gives the product a unique credibility and demonstrated effectiveness at rapidly seeding filter media with the correct bacterial community. A single bottle can cycle a new aquarium in as little as 24 hours when used with ammonia dosing per Dr. Tim's recommended fishless cycling method. The culture requires refrigerated shipping for maximum viability. Available in freshwater and saltwater formulations.
