At the risk of not giving you the answer you want, it depends. The conditions in your water will dictate how well the bacteria you are adding will do. They might get their lunch money stolen and beaten up on day 1 or they could take hold and do very well in your system for much longer. If you want to try it, try it. I have tried a few brands myself. Some seem to do nothing while others seem to have some positive results in the short term. I will never bother buying another bottle of any brand again because it's just silly, but if you have an emergency you might as well try it.Originally Posted by Madmax478
