How often should you dose ammonia to a new tank (after its been cycled) to keep the denitrifying bacteria alive, if you don't plan to immediately add any livestock? If it's worth noting, this tank was started using the Dr. Tims method, dumping a whole bottle of bacteria on day one and dosing ammonium chloride on days 1, 3, and 6, with a 25% water change on day 14. Fish are SUPPOSED to be added on day 9; but we plan to wait longer. So the question is, after day 6, how often should the ammonium chloride continue to be dosed?
