Cycling a fish house with the fish present puts them at great risk of being poisoned by ammonia and nitrite or water treatment Established tanks and ponds house beneficial bacteria as well as our fish. These good bugs perform and produce the nitrogen cycle for us, creating what we call, a cycled fish house, making the environment safe. Only a cycled fish house is capable of becoming, of supporting a healthy ecosystem There are many fish keepers that do everything in their power to keep the cycle from forming in their fish house. Some use products designed to absorb ammonia. Some perform large and frequent water changes to remove ammonia. Some rely on water treatment to convert ammonia, but none of these means are safe or effective The fish free cycle creates an unstable colony of friendly bugs, making for an unpredictable cycle, leaving fish at risk of ammonia and nitrite poisoning Although a live fish cycle offers the friendly bugs a diet derived from healthy waste loaded with enzymes, making for a healthy colony, making for a strong cycle, this method places fish at risk of ammonia and nitrite poisoning During the cycle, fish are exposed to high levels of ammonia and nitrite. We perform daily water changes and use water treatment to convert the dangerous toxins, but if too much water is exchanged, the progress of the cycle is stalled, and if we use too much water treatment, our fish could be poisoned by the treatment itself Water treatment, seemingly innocent, can be just as dangerous as the toxins we’re converting if used improperly. In order for the cycle to complete, the fish will eventually be subjected to increased dosages in a live fish cycle When it works, bottled bacteria create an environment dependent on the product’s use The SEMI live fish free cycle keeps ammonia at controlled levels that are easily converted in the fish house, while a water pump, located out of house becomes established using the fish’s waste Combines the live fish cycle with a fish free cycle to create a fast but safe cycle using your own fish’s waste to build a healthy colony of beneficial bacteria Safe and effective
