As you probably know, cycling a new aquarium can take weeks or even months. For new hobbyists, this can be discouraging because you want to add corals or fish as soon as possible. It is frustrating for even those that have been in the hobby for a long time. Of course, experienced hobbyists know a tank must be cycled, but all hobbyists would agree that the faster a new tank can be cycled, the better.
FritzZyme TurboStart 900 allows you to cycle an aquarium in unbelievably fast amounts of time. It's not that it temporarily cycles or partially cycles. By using TubroStart 900, you can fully cycle your aquarium in as little as five days!
How does TurboStart 900 work? When an aquarium is first set up, any organic material in the aquarium will cause a spike in ammonia that is toxic to fish, corals, inverts, and pretty much any other living thing you want to add to your aquarium. Over time, ammonia eating bacteria will populate the aquarium. The ammonia will be turned into nitrite, and the nitrite will turn into nitrates in a similar way. This process can take several weeks or even two months. TurboStart makes that happen much faster. It introduces the bacteria you need to get your aquarium cycled. This bacteria would populate on its own if you didn't touch the aquarium, but TurboStart introduces a hefty amount so that the populating doesn't take nearly as long. It's a simple solution, but it makes sense. There are, of course, other bacteria products, but TurboStart 900 is one of the most popular because of its effectiveness. Even if you aren't concerned with cycling time, TurboStart 900 ensures your aquarium will have the essential bacteria it needs. Not only does it cycle your aquarium fast, but it helps make sure your aquarium is cycled correctly. This will decrease the chances for algae problems early on.
What are other uses for TurboStart 900? TurboStart 900 is something you should always keep on hand because of its several different applications. Unlike some other cycling products, TurboStart 900 can be used on established tank as well. For example, if you are doing a large water change, you may want to add TurboStart 900 to makeup for lost bacteria. Another reason to use it is adding new fish. Your aquarium might be able to handle five fish well, but adding another three (especially at the same time) may shock the system. By adding TurboStart 900 alongside new livestock, your tank will be able to adapt to the addition much smoother. There are several other situations where you may need to add some extra bacteria such as aggressive cleaning, changing filter media, or medicating. The thing to keep in mind is dosing the correct amount. Fortunately, TurboStart 900 usually doesn't cause problems when overdosed, another benefit to this amazing product.
Directions & Use

For new systems, dose 1 oz (29 mL) per 25 US gallons (38 L). Shake well before dosing. To decrease cycling time, FritzZyme® TurboStart® 900 can be safely used up to 5x recommended dosage.

  • All chlorine and chloramines must be removed from water before adding FritzZyme® TurboStart 900
  • Nitrifying bacteria require ammonia and nitrite to survive; in new systems introduce livestock or another ammonia source. NitroCycle is great for this!
  • Maintain adequate water flow or aeration
  • Discontinue use of skimmer and UV sterilizers for at least 5 days after application
  • Store refrigerated
Additional Information:
  • No contraindications: can be used with all of our other products and meds
  • Safe for use with all species, including plants and invertebrates
  • Systems may be slightly cloudy or have an earthy odor for several hours after treatment
  • Variations of odor and color between bottles is normal, a strong sulfur smell does not mean the bacteria are dead
  • Do not freeze or overheat. Store in a cool, dark place
  • Overdosed? Live nitrifying bacteria are very safe even if overdosed. Observe for any distress, perform small water changes if necessary

Ideal parameters for FritzZyme® TurboStart 900 nitrifying bacteria:
Temperature: 77-86 F (25-30 C)
pH: 7.3-8.0; nitrification is completely inhibited below pH 6.0
Salinity: 15 - 40 ppt (1.011 to 1.030 sg)
Alkalinity (KH): minimum 4.5 dKH or 80.5 ppm KH
Phosphate: above 0 ppm

My TurboStart arrived warm/hot, is it safe to use?
The acceptable safe temperature range per Fritz is 33F to 95F, at which point the higher the temperature and the longer exposure some portion will start to die off slowly. It would take days of exposure at 120F or higher for there to be any loss of bacteria within the product.
