aquavitro® seed™ will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: “new tank syndrome”. seed™ is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrates and nitrites. The bacteria used in competing products are inherently unstable. The conditions necessary for their growth and development fall into a very narrow range of temperatures, pH, organic loads, etc. When any of these parameters are not strictly within the proper range, the bacterial culture quickly crashes and dies. seed™ does not contain any of these short-lived bacteria. The species of bacteria in seed™ are a unique blend, specifically developed for hardiness and their ability to adapt to a wide variety of environmental conditions. The strains thrive in both fresh and saltwater. seed™ contains both nitrifying and denitrifying bacteria, a blend found in no other product. Additionally, seed™ contains facultative bacterial strains which are able to adapt to either aerobic or anaerobic conditions.
