FritzZyme® TurboStart® 700

Once your aquarium is fully cycled, additional dosing of FritzZyme Turbostart is usually not necessary. Adding a dose can be helpful to fortify the biofilter when introducing new fish, after cleaning/changing filters, or if an ammonia or nitrite spike occurs. If your aquarium is stable and ammonia and nitrite levels remain at or near zero, your biofilter is healthy and established, and additional dosing is generally not needed.

As long as the product has not been exposed to freezing or extreme heat, a sealed bottle of FritzZyme® should remain viable up to its best by date. FritzZyme TurboStart 700 is a live product, variation is normal. Odor in the bottle (or lack of odor) does not indicate whether the bacteria are alive.

FritzZyme® Turbo Start 700 is for freshwater use and FritzZyme® Turbo Start 900 is for brackish and saltwater use. Both FritzZyme® TurboStart 700 and 900 work the same natural way, but the species of bacteria differ in order to achieve the best results possible in each environment. By having separate products with optimum species for each environment, the “lag time” for the bacteria to adjust is avoided. If the wrong FritzZyme® is used, you will not achieve the needed ammonia and/or nitrite control. Introduce the correct FritzZyme® as soon as possible. Water changes to remove the incorrect FritzZyme® will not be necessary.

The presence or absence of an odor is not a sign of effectiveness and can vary from batch to batch. If it is within shelf life the product should be fine.

No. Your fish will provide enough ammonia for the nitrifying bacteria to grow and cycle the system. Adding additional ammonia with fish present is not recommended. To cycle a tank without fish (the Fishless Cycling method), we recommend using FritzZyme Turbo Start 700 and Fritz Fishless Fuel as a precise ammonia source.
