Seachem AmGuard 500ml

Seachem Amguard detoxifies toxic Ammonia for 48 hours. High levels of Ammonia can be lethal to fish.

AmGuard safely, rapidly and efficiently removes 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 forty-eight hours. That’s nearly twice as long as our competitor's 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 ionised. 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.

For long term ammonia control, use Seachem Stability and Matrix. Use Ammonia Alert or MultiTest: Free & Total Ammonia to directly monitor levels of free ammonia. AmGuard also removes chlorine and chloramines.
