About FritzZyme® TurboStart® 900 Saltwater

FritzZyme® TurboStart® 900 contains the same proven strains of effective, live nitrifying bacteria as FritzZyme® 9, but at 15 times the concentration. FritzZyme® TurboStart® 900 reduces fish loss due to toxic levels of ammonia and nitrite.

Establishing colonies of nitrifying bacteria the without FritzZyme® can take weeks; FritzZyme® TurboStart® 900 completely cycles aquariums in five days or less, allowing for safe, immediate addition of livestock. FritzZyme® TurboStart® 900 may be added to new tanks or established systems any time the biofilter needs fortification including: after water changes, aggressive cleaning, adding new livestock, medicating or changing filter media.

Directions & Dosage

Chlorine and chloramines are lethal to FritzZyme® TurboStart® bacteria and must be completely removed before addition.
Turn off UV sterilizers and protein skimmers before use and for 5 days after each introduction of FritzZyme® TurboStart® 900.
Shake bottle, add 1 oz. (29 ml) TurboStart® per 25 gallons (95 L) of water.
Add animals after acclimating. Do not overcrowd tank. Do not overfeed.
Test water parameters regularly.
To decrease cycling time, FritzZyme® TurboStart® 900 can be safely used up to 5x recommended dosage.

NOTE: Systems may be slightly cloudy or have an earthy odor for several hours after treatment.

Live product. Keep refrigerated. Do not freeze. Refrigerated life is 6 months. Use before expiration date on bottom of bottle.

See below for frequently asked questions regarding FritzZyme® TurboStart® 900 Saltwater.

  • What the reason to turn off the protein skimmers when using TurboStart 900?

    The nitrifying bacteria will be in the water column for several days, depending on temperature and flow, so the skimmer could remove some of the bacteria before it has time to settle and begin colonizing the media and surfaces.

  • My nitrites won’t go down after weeks of cycling. Will TurboStart help me get rid of the nitrites?

    Hello, I started cycling my 20G cube nearly 3 months ago with Dr Tims, realreef rock and arag-alive substrate. After week 1 I had 0 ammonia, 5+ nitrite and 15 nitrate. Those parameters have stayed there ever since. I started dosing Microbacter7 daily for the last 2 months with no change in nitrites. Do you think your TurboStart product would help me get rid of the nitrites at this point? I added a single firefish last week and it is still alive and healthy. Some have said sometimes I need a fish to get rid of the nitrites but the level hasn’t changed…this is why I’m looking for yet another bacteria source to get rid of these nitrites.

    TurboStart will do nothing but help, but if for some reason your system is lacking something the bacteria need (phosphates for example) you can get a stall in nitrite conversion and even Turbo may not push it over.  Adding the fish itself doesn’t help directly with nitrite, but feeding the fish will.  We have seen situations where all phosphates have been depleted in a sytem and nitrites stall.  People knock phosphates, but absolute zero in not good as the bacteria need some phosphates to function.  You feeding the fish should add some phosphates and should push it over.  I would stop dosing the Microbacter as this product is more than likely heterotrophic bacteria and may be competing for phosphates with the nitrifers.

  • How do I store it?

    Nitrifying bacteria are delicate, they are “vegetative cells” and do not form a protective coat or “spore” as many non-nitrifying bacteria do. For this reason, FritzZyme® has a limited shelf life and must be protected from freezing (32°F) and overheating (110°F). Room temperature out of direct sunlight is sufficient for storage. Ideal storage temperature is 45 to 55°F.

  • Does the color or smell change the effectiveness or remaining shelf life of FritzZyme®?

    No. The smell may range from none to a very strong pungent odor and the color from a rosy red to a grayish black. We have seen the odor and color ranges mentioned above to be equally effective. The true test of the product effectiveness is its ability to convert ammonia and/or nitrite. If the product has not expired and has been handled properly, it will be effective in the aquarium.

  • 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.

  • 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); 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.

  • How does FritzZyme® work?

    FritzZyme® allows your tank to duplicate nature. FritzZyme® “seeds” the biological filter with sufficient numbers of beneficial nitrifying bacteria so it can begin to remove ammonia and nitrite. Because the time required for the bacteria to become established is drastically reduced, fish may be introduced much sooner. When adding more fish or other bio-load to an aquarium, the addition of FritzZyme® adds more bacteria to the biofilter, thus preparing it to be able to handle the increased ammonia production.

  • How long has Fritz Industries, Inc. been working with nitrifying bacteria?

    Fritz Industries, Inc. has been working with nitrifying bacteria for over 26 years and has constantly worked to perfect culturing techniques while obtaining maximum production with superior packaging of a stabilized product.

  • How often should I use FritzZyme®?

    After the initial dosage of FritzZyme® to seed the biofilter, additions are only needed if more animals are added to the system, the efficiency of the biofilter has been reduced by medications or the biofilter has been disturbed (e.g., changing the media of a canister filter).
