Review on 1-Gallon Kordon #31262 AmQuel - Effective Aquarium Ammonia Detoxifier by Jason Selby

This material is great for water changes. I haven't had any problems with chlorine and my ammonia levels are acceptable. With a 180 gallon tank I use it a lot so buying in bulk is quite a bargain. I saw it at Petco for about the same price so I may go there in the future to avoid shipping. A note about packaging. The lid was not sealed with tape and there was very little leakage. I've seen this in other large liquid containers. I bought a Flourish Excel with the lid sealed with tape and there was no leakage.
