The Science

AmGuard specifically targets the free form of ammonia, which is the toxic portion harmful to aquatic life. It converts ammonia into a non-toxic compound that your biofilter can process safely. Unlike some other products, AmGuard does not alter pH, and it remains active for up to 72 hours. For accurate monitoring, use in conjunction with an ammonia test kit. For long-term ammonia management, pair AmGuard with Seachem Stability and Matrix to maintain a stable, healthy aquarium environment.
