AmmoBuster Extreme - The one step water conditioner that does it all! It will not only eliminate ammonia, chlorine and chloramine, but detoxify heavy metals, even copper. At the same time, AmmoBuster Extreme will replace a fishes protective “slime coat”, add essential electrolytes, boost alkalinity, and reduce fish stress. It even neutralizes nitrite! Ideal for handling high ammonia levels in newer aquariums where the waste reducing bacteria populations are not yet adequate.
