Frequently Asked Questions regarding Fritz Aquatics FritzZyme 9 Saltwater Nitrifying Bacteria
Q. How often should I use FritzZyme Nitrifying Bacteria?
A. After the initial dosage of FritzZyme Nitrifying Bacteria 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).
Q. Can I use copper medications with FritzZyme Nitrifying Bacteria in my marine aquarium?
A. The use of any medication in either fresh or saltwater aquariums should be avoided until the biofilter has become well-established. Any medications or water conditioners containing copper, formaldehyde, malachite green and methylene blue are extremely inhibitory or lethal to nitrifying bacteria. Occasional outbreaks of protozoan parasites during this period are usually due to ammonia-related stress. Treating with one of these chemicals only adds to the problem by allowing ammonia to reach toxic levels. It is advisable to remove infected fish to a quarantine or hospital tank for treatment. Once nitrifying bacteria have become well established, they will become tolerant to low levels of copper.
Q. Can I use chemical ammonia removers with FritzZyme Nitrifying Bacteria?
A. Chemical ammonia removers work by converting poisonous ammonia to non-toxic compounds. Nitrifying bacteria may not be able to utilize some of these compounds. The use of ammonia removers will only prolong the time needed to establish the biofilter. Repeated use of these chemicals may also lower the pH of the water. Nitrification will cease if the pH drops below 6.5.
Q. What levels of ammonia and nitrite should I see when using FritzZyme Nitrifying Bacteria?
A. 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.
Q. Do you need a weekly dose every week with FritzZyme Nitrifying Bacteria?
A. Normally, it is not necessary for you to put additional dosages of FritzZyme in your tank once the tank has cycled. Often, aquarium users place additional dosages in their tanks if they are adding new fish, are cleaning their filters or see an occasional ammonia or nitrite spike. If your aquarium is looking great and the ammonia and nitrites are at or near zero, it normally is not necessary to add additional product.
Q. Why does it take so long for an aquarium to cycle without FritzZyme Nitrifying Bacteria?
A. 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.
Q. Why not have a dry version of FritzZyme 7 or FritzZyme 9?
A. 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.
Q. How long has Fritz Industries, Inc. been working with nitrifying bacteria?
A. 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.
Q. What is the difference between FritzZyme 7 and FritzZyme 9 Nitrifying Bacteria?
A. 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.
Q. How does FritzZyme Nitrifying Bacteria compare to other products?
A. FritzZyme Nitrifying Bacteria 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.
Q. Do I need to add an initial ammonia source for the nitrifying bacteria of a new tank?
A. 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 recommended method. Slight increase in ammonia and nitrite levels may occur for a brief period, but they will be well below stress levels.
Q. How does FritzZyme Nitrifying Bacteria work?
A. FritzZyme Nitrifying Bacteria allows your tank to duplicate nature. FritzZyme Nitrifying Bacteria “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 Nitrifying Bacteria adds more bacteria to the biofilter, thus preparing the aquarium to be able to handle the increased ammonia production.
Q. What products should not be used with FritzZyme Nitrifying Bacteria?
A. U.V. sterilizers, foam fractionators (protein skimmers) and ozone generators should not be used for at least 7-10 days after the addition of FritzZyme Nitrifying Bacteria. 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.
Q. How can I tell if the FritzZyme Nitrifying Bacteria has spoiled?
A. Short of being exposed to freezing or very high temperatures, a sealed bottle of FritzZyme Nitrifying Bacteria should be viable up to its expiration date. If there is no conversion of ammonia and nitrite, there is a very slight possibility that the bacteria has died (due to freezing or overheating). More likely, other inhibitory factors may be affecting the bacteria (see above). Alive or dead, FritzZyme Nitrifying Bacteria is non-toxic and completely safe. It will not harm fish or invertebrates, even if accidentally overdosed.
Q. Does the color or smell change the effectiveness or remaining shelf life of FritzZyme Nitrifying Bacteria?
A. No. Though the smell may range from none to a very strong pungent odor and the color from a rosy red to a grayish black, these factors do not affect product effectiveness. 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.
Q. What other products may be used with FritzZyme Nitrifying Bacteria?
A. Chlorine must be removed before adding FritzZyme Nitrifying Bacteria as 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.
