To avoid confusion it should be recognized that there are two products with the AmQuel® name - the original AmQuel which Kordon has been providing since 1985, and the recently invented product AmQuel Plus which is based on a much improved new chemical formula. AmQuel Plus is the latest development in state-of-the-art water conditioning technology and is far beyond what the original AmQuel product does. AmQuel Plus does all that AmQuel does and a significant number of additional tasks as well. .

AmQuel Plus is a remarkable new discovery that is making fresh and saltwater aquarium and pond keeping much safer and simpler. It is doing this by safely detoxifying natural nitrogen compounds in the water, including nitrites and nitrates. Thereby, the use of AmQuel Plus greatly reduces the need for continual water changes, and provides far better water conditions for fishes, aquatic invertebrates, and other life in fresh and salt water.

AmQuel Plus (also referred to as AmQuel +) has the ability to make the "nitrogen cycle"totally nontoxic in aquarium and pond keeping, without interfering with the cycle's process in any way, and without interfering with the beneficial bacteria that are involved with the cycle. AmQuel Plus detoxifies all chlorine and chloramines added to the water by public water utilities and toxic nitrogen compounds that can appear in aquarium and pond water over time, thereby making water changes less necessary, and providing a safer environment for fishes and aquatic life.

AmQuel Plus reduces the problems with "new tank and pond syndrome," which in great part are caused by the nitrifying bacteria in the water. AmQuel Plus makes biological filtration much safer by detoxifying its natural processes. AmQuel Plus does all this without having to be removed, once it is put into the water. It remains totally nontoxic to aquatic life.

AmQuel Plus should be used for setting up aquariums or ponds, for water changes, overcrowded aquariums and ponds, the control of toxic nitrogen compounds commonly found in water while the nitrogen cycle is well as afterwards as nitrogen compounds accumulate in the aquarium and pond water.

Fresh water is a precious commodity and becoming in ever shorter supply. By using AmQuel Plus fewer water changes are needed in aquarium and pond keeping, thereby conserving a valuable resource. For marine aquarists AmQuel Plus greatly helps in decreasing the number of water changes needed, thereby saving on having to prepare sea salt mixes or natural sea water.


AmQuel Plus is harmless to plants, fishes, invertebrates (including corals and sea anemones), and other aquatic life forms. This product is safe for use in aquariums and ponds and will not interfere with biological filtration or its bacteria. When AmQuel Plus detoxifies ammonia, nitrites, nitrates, and other organic compounds, it breaks the links of molecules apart. The nitrifying bacteria do not know the difference and eat the parts, just as they would the whole original compounds.

Where AmQuel Plus is particularly useful is in its detoxification of all nitrates in the water. There are not sufficient bacteria in the aquarium (fresh or salt water) and pond water to do this. In the past the only way to get rid of nitrates from aquariums and ponds was by water changes. Now this can be done in a few minutes with AmQuel Plus. This leaves the main reason for making water changes (now needed less frequently) to replacing trace elements in the water.

AmQuel Plus is recommended to be used with Kordon's NovAqua Plus because they mainly do different functions that collectively are needed in aquarium and pond keeping. NovAqua Plus is most important for treating tap water that comes from public water utilities that has accumulated toxic metals from water pipes, and in providing health aids to the fishes and aquatic invertebrates. See NovAqua Plus for further information. AmQuel Plus and NovAqua Plus are provided as separate products because they cannot be combined and stored together, without loss of efficacy.
