1.  Do I need to add an initial ammonia source for the nitrifying bacteria of a new tank?

Your fish will provide the necessary ammonia. The advantage of using FritzZyme® is that you can add the fish right away to a new tank (without adding any ammonia) and this is the method we recommend. Slight rises in ammonia and nitrite may occur for a brief period, but they will be well below stress levels.

2.  How soon may I stock my tank with a full load of fish?

Nitrifying bacteria must be present in sufficient numbers in your biofilter to handle the ammonia generated by a full load of fish, otherwise the ammonia can rise to lethal levels. Naturally this requires 3-4 weeks for freshwater, and 4-8 weeks for saltwater. FritzZyme® TurboStart™ will dramatically shorten this delay from weeks to several days. Recommended initial livestock loadings are dependent on several factors; the amount of rock in your tank, species of livestock, sump area, filter size and type, etc. If initially adding a large livestock load it is recommended to feed minimally for the first week, allowing the nitrifiers to establish themselves.
