EBaySEACHEM Stability 100ml/325ml/500ml -Specially selected strains of bacteria -It instantly breaks down compounds of organic matter -It prevents the syndrome of the new reservoir Stability is a specially selected strains of bacteria that quickly and effectively begin the biological filtration process, which prevents the most common cause of fish death, ie the "new tank syndrome". The preparation was created especially for marine and freshwater aquariums. It contains a mixture of aerobic, anaerobic and facultative bacteria (able to carry out metabolic processes both under aerobic and anaerobic conditions), which accelerate the decomposition of organic matter, ammonia, nitrates and nitrites. Unlike other products of this type, Stability does not contain strains that produce hydrogen sulphide. It is safe for aquatic organisms (including plants) and cannot be overdosed. Work on the development of its recipe took almost 10 years. Bacteria contained in similar preparations are characterized by limited strength and low tolerance to changes in temperature, pH, level of organic components, etc. If any of these parameters is not within the appropriate range, bacterial cells die quickly. When using Stability, this risk does not occur, as it does not contain this type of bacterial strain. The microorganisms found there are characterized by a wide range of tolerance to changes in environmental factors. A large amount of organic matter even stimulates them to more intensive growth and multiplication. Stability is suitable for use in marine and freshwater tanks. Directions for use: When setting up a new tank, on the first day add 1 cap (5 ml) for every 10 liters of aquarium capacity. After that, add 1 cap for every 80 liters of tank capacity during a week. During this period, you can start introducing fish and other aquatic organisms. Then add 1 cap for every 40 liters of tank capacity once a month or during each water change, as well as when introducing new fish and after finishing medications. It's good to have a well developed mindset about aquarium and lifestock in it. Really it is not about just water, light and fertilizers  Keeping it all together is to have an understanding of what you think is happening in your water system.  Everyone has a little diffrent ideas of that, so as long as you have your own, and you can support that idea - that's great.  And when you have your underlying idea, you can build that system to support that idea of how to manage your tank.  Before dispatching you will be provided with full info about your package: shipping number and details to track your delivery.
