Seachem AmGuard 4L

AmGuard safely, rapidly, and efficiently detoxifies toxic free ammonia. It is safe to use during tank cycling and is ideal for treating emergency situations. AmGuard is the strongest liquid ammonia binder on the market. It works within minutes to detoxify free ammonia, and it doesn’t degrade for nearly 72 hours. That’s at least twice as long as our competitors’ products. Unlike competing products, AmGuard converts it into a safe, non-toxic form that is readily removed by the tank’s biofilter. It does not alter pH.
