A step above AmQuel, non-toxic advanced formula AmQuel+Plus® by Kordon not only removes chlorine, chloramines and ammona, but also "eliminates nitrate and nitrite, and removes toxic organics in older aquarium water, for fewer water changes". When using AmQuel+Plus® you'll find it has an unusual odor, but this gradually disappears once added to water. It can also moderately reduce oxygen in water during the first hours of use, and therefore its important to always maintain good water circulation or aeration, and allow a 24 hour period between single dose applications.
