Seachem AmGuard

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.

Ammonia can exist in two forms: free and ionized. It is only the free form that is toxic. Traditional ammonia test kits convert all ammonia to free ammonia by raising pH to 12–14; at this pH AmGuard™ cannot function and thus a false positive reading will result. 

• Detoxifies ammonia for up to 72 hours
