Detoxifies ammonia for up to 72 hours

Ideal for emergency situations. More effective than any other ammonia-binding product. The most concentrated product on the market.

AmGuard™ safely, quickly, and efficiently detoxifies toxic free ammonia. It can be safely used during aquarium transitions and is perfect for treating emergencies. AmGuard™ is the strongest liquid ammonia binder available. It works within minutes to detoxify free ammonia and does not break down for nearly 72 hours. That’s at least twice as long as competitor products. Unlike competing products, AmGuard™ converts ammonia into a safe, non-toxic form that can be easily removed by the tank's biofilter. It does not alter pH levels.

Ammonia can exist in two forms: free and ionized. Only the free form is toxic. Conventional ammonia test kits convert all ammonia into free ammonia by raising the pH to 12-14. At this pH level, AmGuard™ cannot function, leading to a false positive result. For long-term ammonia control, use Seachem Stability® and Matrix™. Use Ammonia Alert® or MultiTest™ Free & Total Ammonia to directly monitor free ammonia levels. AmGuard™ also removes chlorine and chloramines.
