Seachem AmGuard 500ml Instant Ammonia Detoxifier for Aquariums

Seachem AmGuard 500ml is a powerful, fast-acting ammonia detoxifier designed to handle sudden ammonia spikes and emergency situations in both freshwater and marine aquariums. It begins working within minutes, making it an essential safeguard for protecting fish, corals, and invertebrates from toxic ammonia exposure.

AmGuard binds ammonia for up to 72 hours, converting it into a safe, non-toxic form that can be gradually processed and removed by the aquarium’s biofilter. Unlike many chemical treatments, it does not alter pH, ensuring water parameters remain stable while ammonia levels are brought under control.
