Ammonia will kill your fish. This product also neutralizes ammonia and the pH of your water. It is a powder that can be easily dosed and added to the aquarium water. peace of mind. It works so well that I don't use it with every water change, but I do have chlorine-free spring water. If you have chlorine in your water it will also neutralize the chlorine so you can use it with every water change to protect your fish.
