About FritzZyme® 9 Saltwater

FritzZyme® 9 contains saltwater-specific strains of live nitrifying bacteria proven to reduce fish loss due to toxic levels of ammonia and nitrite. Nitrifying bacteria can take weeks to naturally establish colonies in new aquariums while ammonia and nitrite can reach lethal levels in only a few days. FritzZyme® 9 provides the proper balance of bacteria proven to rapidly seed biofilters, greatly reducing the natural cycle time allowing for safe, immediate addition of livestock.

Fritz Industries was the first company to pioneer commercial-scale cultivation of nitrifying bacteria and has remained one of only a few in the world with continuous production for over 30 years. FritzZyme® 9 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. FritzZyme® 9 contains live saltwater-specific species of nitrifying bacteria.

Directions & Dosage

For a new system, dose 4 oz (119 ml / ½ cup) per 5 US gallons (19 L). For a large livestock system, new system dosage may be safely increased up to 10x. For established systems, use 2 oz (60 ml / ¼ cup) per 5 US gallons (19 L).

NOTE: Live product. Do not freeze or overheat. Store in a cool, dark place. Use before expiration date.

FAQs

FAQs

See below for frequently asked questions regarding FritzZyme® 9 Saltwater.

  • Why not have a dry version of FritzZyme® 7 or 9?

    FritzZyme® contains true nitrifying bacteria. These bacteria have a low survival rate when dried or freeze-dried. Low survival rates mean very few viable “living” nitrifying bacteria would be added to the aquarium. Although competitors claim to have dry versions, tests have shown that these products actually do not establish the biofilter significantly faster than the biofilter would have established on its own.

  • What is the difference between FritzZyme® 7 and FritzZyme® 9?

    FritzZyme® 7 is for freshwater use and FritzZyme® 9 is for brackish and saltwater use. Both FritzZyme® 7 and 9 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.

  • 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 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).

  • Why does it take so long for an aquarium to cycle without FritzZyme®?

    In comparison to other types of bacteria, nitrifying bacteria grow very slowly. Under optimal conditions, it takes fully 15 hours for a colony to double in size! By adding FritzZyme® nitrifying bacteria, you are adding bacteria to your system in amounts that would have taken weeks to naturally grow.

  • What if my nitrites will not go down in my freshwater aquarium treated with FritzZyme®?

    In freshwater, we occasionally run across this situation, and the first thing we recommend is testing your alkalinity. In aquariums with an alkalinity below a 4.5 dKH (1.6 Meq/l), the bacteria that convert the nitrite to nitrate simply stop the conversion process. We have found that after raising alkalinity to a minimum of 4.5 dKH (1.6 Meq/l) but ideally 5.6 dKH (2.0 Meq/l), nitrite conversion proceeds rapidly. In very, very rare cases the nitrite portion of the cycle remains stalled. In that situation, check your phosphate levels. Nitrifying bacteria, like all living organisms, need trace amounts of phosphate to function. A fishless cycle using ammonium chloride and RO/DI water may have 0.00ppm phosphates and will not complete the cycle. Even a trace amount of phosphate will allow the nitrifying bacteria to rapidly convert nitrite to nitrate. Fish food is a source of phosphate and Fritz pH Neutralizer contains phosphates. ⅛ to ¼ the standard dose would provide enough phosphate for nitrite conversion.

  • What levels of ammonia and nitrite should I see when using FritzZyme®?

    You will see the normal “new tank syndrome” time greatly reduced or completely eliminated. The ammonia and nitrite levels, if present, will be well below stress levels. Problem systems will recover in a matter of days without extensive water changes.

  • 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.

  • What sets Fritz Industries’ nitrifying bacteria products apart from other competitors?

    Fritz Industries is the only known company growing viable nitrifying bacteria with a shelf life of over 30 days, and no other company can compare to the concentration levels of viable bacteria.

  • How does FritzZyme® compare to other products?

    FritzZyme® was the first product on the market to rapidly establish biological filters in aquatic systems. Having been on the market for over 15 years, it is the only time-proven product of its kind, becoming known as “the bacteria that works.” Since over 75% of the ammonia generated within the aquarium comes from direct excretion from the fish, it only makes sense to use bacterial products which provide the nitrifying bacteria to utilize this ammonia. If the product will not utilize ammonium chloride, it will not utilize the excreted ammonia. Therefore, although other products have been introduced on the market with many claims, be assured there is only one tested, proven FritzZyme®.

    In addition to FritzZyme® being sold throughout the pet industry, the Fritz Pet division supplies FritzZyme® to professional fish, shrimp and lobster farms, city aquariums, universities, research facilities and zoos throughout the world. Many entertainment parks are also regular users of FritzZyme®. To these professionals, having a reliable product to establish and maintain their systems is of vital importance. They rely on FritzZyme®.

  • What products should not be used with FritzZyme®?

    U.V. sterilizers, foam fractionators (protein skimmers) and ozone generators should not be used for at least 7-10 days after FritzZyme® additions. This allows the bacteria time to become attached so that they will not be killed or removed by these types of equipment. Many medications will also reduce the efficiency of the biofilter.

  • What other products may be used with FritzZyme®?

    Chlorine must be removed before adding FritzZyme® (chlorine kills bacteria). FritzGuard® or Fritz Chlorine Remover may be used for this purpose. Fritz pH blocks for pH control, Fritz Super Salt for marine systems, Fritz Super Clarifier and Fritz Trace Elements may also be used without any adverse effect to the biofilter.
