The original product that established the state-of-the-art in water conditioning technology regarding ammonia removal.

To avoid confusion it should be recognized that there are two products with the Amquel name - the original AmQuel and the recently improved product AmQuel+. AmQuel+ does all that AmQuel does and a significant number of additional tasks as well. See in "ABOUT CONDITIONERS " the section "Comparison Between AmQuel and AmQuel+".

Kordon AmQuel, developed about 20 years ago, is the original product that established the state-of-the-art in water conditioning technology regarding ammonia removal. AmQuel quickly and effectively removes ammonia, chlorine and chloramines (three of the most toxic chemicals commonly found in aquatic systems) from freshwater and salt water. AmQuel is the first to be a true one-step liquid ammonia and chloramine remover that is simple to use. AmQuel is completely unlike dechlorinators which claim to "remove" chloramines. These products only break the chlorine-ammonia bond of chloramines by simple dechlorination, leaving the ammonia in the water. The resulting ammonia must be removed by bacterial action which can take days or weeks or by adsorption on granular or powdered zeolites (clinoptilolites). In addition, AmQuel functions as well in salt water as it does in fresh water; whereas zeolites do not remove ammonia in salt water.

Contains 100% sodium hydroxymethanesulfonate.

The "Standard Dose" of AmQuel is one teaspoon (5 ml) per 10 gallons of fresh or salt water, or one liquid ounce (30 ml) per 60 gallons of water, or one cup (8 liquid ounces - 20 ml) per 480 gallons of water. For other measurements estimate the amounts needed, such as 1/4 teaspoon for 2.5 gallons of water, or 3 teaspoons for 30 gallons, etc.
  • To remove chlorine and chloramines (chlorine combined with ammonia) out of the tap from public water supplies add one Standard Dose (see definition above) to the water to break the bond between the chlorine and ammonia, and to remove all the chlorine, and ammonia that may be in public water supplies. This will remove up to 3 mg/L chloramines (as monochloramine, NH2Cl). No greater dose is needed for removing chloramines or chlorine from public water supplies.
  • To remove toxic ammonia compounds that build up in aquariums and ponds from the excretion of body wastes by fishes, invertebrates, bacteria, and other aquatic organisms start with a Standard Dose (see definition above). This Standard Dose not only removes the chlorine and chloramines described above, but will also remove (detoxify) at the same time 1.0 mg/L (= approx. 1.0 ppm) of all ammonia compounds in fresh or salt water. Use multiple doses to remove more than 1.0 mg/L ammonia from the water.

    It is suggested that the ammonia concentration of the water be tested prior to the addition of AmQuel to determine how much AmQuel is needed. Also see Contraindications for when there may be problems in the use of AmQuel). [sentence relocated] The pH of the water being treated affects the speed at which AmQuel removes ammonia. The lower the pH, the slower AmQuel works. At a pH of 7.0 (neutral) AmQuel will remove the ammonia in less than 5 minutes. Several minutes more are needed at higher pHs.
  • To remove toxic nitrite, nitrate and other organic compounds that build up in aquariums and ponds from the excretion of body wastes by fishes, invertebrates, bacteria, and other aquatic organisms use AmQuel+.
AmQuel is stable indefinitely when stored in a cool, dark area away from heat and direct sunlight. AmQuel must be kept tightly closed when not in use.

AmQuel is harmless to plants, fishes and invertebrates. This product is safe for use in aquariums and ponds and will not interfere with normal biological filtration. AmQuel is compatible with NovAqua and PolyAqua. Use caution when adding liquid AmQuel to water that has a poor buffer reserve (as indicated by problems maintaining a stable pH). Using AmQuel in these conditions can cause a sudden lowering of pH. To prevent a pH drop, use either AmQuel Plus Buffers or Amquel+. AmQuel may affect the dyes in certain types of cotton fabrics. This happens for the same reason that Ammonia test kits using the Nessler reagents do not work with AmQuel or AmQuel+. These products reduce the coloring agents used in the Nessler reaction test kits, and apparently in a very small selection of cotton based fabrics.

AmQuel should not be added to water containing active, therapeutic dosages of chemical dyes such as methylene blue, acriflavine, potassium permanganate or malachite green, since AmQuel will interfere with their proper performance. Combining AmQuel with these dyes will not result in toxic chemical by-products. AmQuel is compatible to use with all water quality test kits except for the ammonia test kit that uses Nessler reagents that read in shades of amber or yellow, and the oxygen kit that uses Winkler reagents. Residual AmQuel and its reaction products are incompatible with the Nessler and Winkler-type test reagents, resulting in false, high ammonia and low oxygen concentration readings. All other types of test kits produce accurate test results, such as ammonia test kits using salicylate-type reagents. Kordon`s AquaTru Test Kit #35970 for salt water and #35980 for fresh water are recommended for accurate test results. AmQuel will temporarily (for approximately 12 hours) lower redox. (For more information see "About Conditioners")

TOXICITY:AmQuel is non-toxic when used as directed. Over the past twenty years thousands of species of freshwater and marine fishes, invertebrates and plants have been exposed to AmQuel with no toxic effects. It does not reach toxic levels even in cases of accidental or purposeful overdosing. AmQuel is non-toxic to humans and no special precautions are necessary in handling this product.

There are two Dry AmQuel+Buffers products: no. 31643 4.5 oz, and no. 31648 10 oz. These products provide AmQuel with the buffers needed to keep the pH from becoming more acidic due to the acidity of the AmQuel formulation. (See also AmQuel+, which does not require buffering in its use).

AmQuel is available in bulk pure dry form for professional and commercial use. See the section on AquaVet for listings and further information.

As a general rule, when using tap water in which chlorine and chloramines are present, but not nitrites, nitrates or other organics -- then it is safe to use the less expensive AmQuel. If there is the possibility of nitrites, nitrates and other organics being involved, then Amquel+ is recommended.

When using AmQuel with tap water, add AmQuel to water at the recommended dosage to remove ammonia, chlorine and chloramines. To fully condition tap water, add NovAqua as well. Use AmQuel or AmQuel+ and NovAqua each time a water change is made. If the tap water contains both ammonia and nitrite (this is becoming more common in public water supplies) then AmQuel+ should be used instead of AmQuel. Also see AmQuel+ as to when it should be used.

AmQuel or AmQuel+ and NovAqua should be added to tap water used for shipping fish and invertebrates. If the fish are crowded or prone to bump into or abrade each other, PolyAqua should be added to both the shipping water and the aquarium or holding tank after shipments are received. NovAqua and AmQuel, when used together, will reduce stress, osmotic and pH shock, probability of infection, and neutralize ammonia, chloramines, chlorine and heavy metals. PolyAqua should be used to handle abrasions, bruises, and frayed fins of fishes.

When using water from natural conditions for field collecting the use of AmQuel in holding and shipping water will reduce stress in fishes and invertebrates due to ammonia intoxication. If fish will be held for days in containers, AmQuel+ should be used, because it will remove (detoxify) nitrites and nitrates as well. In addition, PolyAqua should be used in holding and shipping water for optimum protection against abrasions, bruises, and frayed fins in fishes.

Using Amquell

I have had aquariums all my life off and on. I have always used Amquell because I am very happy with the way it performs in the treatment of my water. Always been a fan of it and will continue to use it as long as it is available.

happy fish

I have used this product for 20 yrs. or more and have never had a problem with it. I use it whenever I add or change part of the water in my aquarium. I like the fact that it works instantly. I don't have any fancy fish, just very happy goldfish that stay with me for 10 to 13 yrs. or more and grow to be 10" to 13" in size. I lost one that I had for 10 yrs. in the 94 earthquake It was 13" or more in length. I have 3 right now. They seem to grow at different rates. I got them all at the same time and the same size, however one is a good 10" long while the others lag behind at 5" and 7". I only buy feeder fish which are destined to become another pets meal. I feel like I am saving them from a bad ending, kind of like when you go to a pound to save a lost puppy.

AmQuel works!

At the moment, I primarily keep multiple bettas in unfiltered environments of about 2.5 gallons each and AmQuel is the best product I have used to control ammonia and keep it at zero in between weekly water changes. I like it as well because I accidentally killed a number of fish using AmQuel+ (a differently formulated product) because the product significantly diminishes the oxygen level in the water to the point where the fish couldn't breathe. Both are great products when used appropriately and AmQuel is a terrific choice that can be added directly to the environment for fast results and is harmless.
