About FritzPond Ammonia Remover

Fritz Pond Ammonia Remover instantly neutralizes ammonia, chlorine and chloramines, protecting fish and other aquatic life in ponds and water gardens. Safe for live plants and pets when used as directed. Ammonia is produced by decomposing plants, algae, fish waste and uneaten food. High ammonia levels often occur in new ponds or in an established pond when adding new livestock, when a filter stops working due to power or mechanical failure or if existing beneficial bacterial colonies are lost due to the use of medications or sudden change in water conditions. Fritz Pond Ammonia Remover will not alter pH or deplete oxygen levels. FritzPond Ammonia Remover is a true complete water conditioner that not only neutralizes toxic ammonia but also the chlorine and chloramines found in tap water. Fritz Pond Ammonia Remover is extremely safe even when overdosed.

Also available in a dry powder.

Directions & Dosage

Use 5 mL (1 tsp/1cap) per 20 U.S. gallons (76 L). Each cup treats 960 gallons. Using this dosage, 1.0 mg/L ammonia will be instantly eliminated, as well as chlorine and chloramines. For areas with very high chlorine levels, or in emergency situations with very high ammonia levels, dosage can be safely increased or repeated up to 5x.

  • For best results, add FritzPond Ammonia Remover to tap water in a separate container before adding water to pond
  • No equipment restrictions necessary
  • No contraindications: can be used with all of our other products and meds
  • Handy when using medications that affect the bio filter: avoid water changes by adding FritzPond Ammonia Remover to detoxify 1 ppm ammonia per dose
  • Easy measuring: the 4 oz, 8 oz and 16 oz bottle caps are approximately 5 mL volume
  • Overdosed? It is safe to increase dosage up to 5x. Observe livestock for distress, perform small water changes if needed
  • Test with: chlorine test kit, salicylate-type ammonia test kit (those with yellow/green color charts) and avoid Nessler-type ammonia test kits (those with yellow/amber color charts)

See below for frequently asked questions regarding FritzPond Ammonia Remover.

  • How much ammonia is too much?

    Any measurable or detectable amount of ammonia is too high and can stress livestock. Any time ammonia is detected, emergency action should be considered to reduce the danger. The presence of detectable levels indicates that your biofilter is not working adequately for several reasons. One, your tank has not yet cycled, or, two, the filter is not functioning adequately, which means it is too small for the amount of livestock you have, is working incorrectly, clogged, etc. Fixing the problem with your filter is as important as taking care of the high ammonia.

  • Do temperature and pH affect ammonia?

    Ammonia varies in toxicity at different pH and temperature of the water. For example, ammonia (NH3) continually changes to ammonium (NH4+) and vice versa, with the relative concentrations of each depending on the water’s temperature and pH. Ammonia is extremely toxic; ammonium is relatively harmless. At higher temperatures and higher pH, more of the nitrogen is in the toxic ammonia form than at lower pH.

    Standard test kits measure total ammonia (ammonia plus ammonium) without distinguishing between the two forms. The following chart gives the maximum long-term level of ammonia-N in mg/L (ppm) that can be considered safe at a given temperature and pH. Again, note that a tank with an established biological filter will have no detectable ammonia; this chart is provided only for emergency purposes. If your levels approach or exceed the levels shown, take emergency action IMMEDIATELY.

    Percent of ammonia from ‘total ammonia’

    Temp C°/0° pH - 6.5 pH - 7.0 pH - 7.5 pH - 8.0 pH - 8.5 pH
    20°C (68°F) - 0.13 - 0.40 - 1.24 - 8.82 - 11.2
    25°C (77°F) - 0.18 - 0.57 - 1.77 - 5.38 - 15.3
    28°C (82°F) - 0.22 - 0.70 - 2.17 - 6.56 - 18.2
    30°C (86°F) - 0.26 - 0.80 - 2.48 - 7.46 - 20.3

    Generally, any value above 0.5 is dangerous.

  • What bacteria is responsible for converting ammonia to nitrite?

    The bacteria responsible for converting ammonia to nitrite in freshwater are from the genus Nitrosomonas; in saltwater Nitrosococcus are responsible. These bacteria are rod-shaped chemolithoautotrophs with an aerobic metabolism. While they do not grow by photosynthesis, their unusual metabolic behavior involves burning ammonia with oxygen. Long, thin membranes inside the bacteria’s cell use electrons from ammonia’s nitrogen atom to produce energy. In order to complete cell division, they must consume vast amounts of ammonia, making the division process last for several days. The cells grow either in pairs or short chains. In nitrification, the ammonia-oxidizing bacteria in Turbostart play the role of oxidizing ammonia to nitrite, which is then converted to nitrate by other bacteria.

  • Is it possible to add an initial ammonia source without using fish?

    Yes, you can. Add ammonium chloride so that levels reach 2 to 4 ppm along with FritzZyme®. When ammonia and nitrite are near 0 ppm, add ammonium chloride one more time, bringing the level back up to 2 to 4 ppm. Once the ammonia and nitrites reach zero, the biofilter is established and ready for animals (time is less than one week). NEVER add ammonium chloride to a tank containing fish.

  • Can this be overdosed?

    The dosage of FritzPond Ammonia Remover can be increased by up to 5x the recommended amount.

  • How does ammonia affect my aquarium?

    Ammonia poisoning is one of the biggest killers of aquarium fish. Toxic levels of ammonia occur most often when an aquarium is newly set up. Known as “New Tank Syndrome,” these fish are poisoned by high levels of ammonia (NH3) that is produced by the bacterial mineralization of fish wastes, excess food, and the decomposition of animal and plant tissues. Additional ammonia is excreted directly into the water by the fish themselves. However, it can also occur in an established aquarium when high amounts of livestock are added (overwhelming the existing biological filter), filter failure due to power or mechanical failure, or if bacterial colonies die off due to the use of medications or sudden change in water conditions.

    The effects of ammonia poisoning in fish are well documented. These effects include:
    *Extensive damage to tissues, especially the gills and kidney
    *Physiological imbalances
    *Impaired growth
    *Decreased resistance to disease

  • If I remove all ammonia, will it harm the bacteria colony?

    FritzPond Ammonia Remover binds with ammonia making it harmless to the inhabitants while still bioavailable to the beneficial bacteria.

  • Where does ammonia come from?

    Ammonia comes from fish respiration and decomposing organic wastes such as fish feces, leftover food, dead plants and animals, etc.

  • What do I dose if my ammonia is extremely high?

    Dilute the ammonia concentration by performing a water change. FritzPond Ammonia Remover can be added up to 5x the recommended amount safely for high ammonia concentrations.

  • What are the common signs of ammonia poisoning?

    Ammonia poisoning is one of the leading causes of death in aquarium fish. It is important to know the causes and effects of ammonia toxicity so that the aquarist can recognize and take immediate action.

    The common signs of ammonia stress are easily detected:
    *Loss of appetite
    *Hovering at the bottom of the tank (especially for surface-dwelling fish)
    *Gasping at the surface
    *Inflamed gills
    *Red streaks or inflammation in the gills
    *Inflamed eyes or anus

  • How long should I wait after treating water to add to tank?

    Treated water can be added to the pond immediately after mixing with FritzPond Ammonia Remover.

  • Can I use this with Aquarium Solutions Ich-X?

    Aquarium Solutions Ich-X contraindicates sulfinate- and sulfoxylate-based water conditioners with their product. Which Fritz water conditioners are safe?

    Fritz Guard - SAFE; this is a thiosulfate conditioner and won't affect the medication

    Fritz ACCR - NOT SAFE; this is a sulfinate-based conditioner and can affect the medication

    Fritz Complete - NOT SAFE; this is a sulfoxylate-based conditioner and can affect the medication

    Fritz Concentratred Chlorine Remover - SAFE; this is a thiosulfate conditioner and won't affect the medication
