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.
