AmQuel+ is the latest development in state-of-the-art water conditioning technology and is far beyond what the original AmQuel product does. AmQuel+ does all that AmQuel does and a significant number of additional tasks as well. AmQuel+ 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 that before could not be effectively detoxified. Thereby the use of AmQuel+ greatly reduces the need for continual water changes and provides far better water conditions for fishes aquatic invertebrates and other life in fresh and saltwater.
