    I'm looking to boost my de-nitrifying bacteria after my system crash. My Question is; Does Cycle replace or add the correct bacteria or is the bacteria in cycle a different type that will only aid for the short term and then die off?

    Thanks
    Jason

    Marinelands Biospira is supposed to work. It contains the same type of bacteria that is found naturally in live rock. I've heard nothing but good things about this product from people. Its the only bacterial product that has to be refrigerated.
