Seachem – AmGuard
AmGuard™ safely, rapidly and efﬁciently detoxifies 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 72 hours. That’s at least twice as long as our competitors’ 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 ionized. 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.
Sizes: 100 mL, 250 mL, 500 mL, 4 L
Use 1 capful (5 mL) for every 200 L (50 US gallons) daily or as needed to reduce ammonia.
ADVANCED: If you have an Ammonia Alert® that is reading “Alert”, then use 1 capful (5 mL) for every 400 L (100 US gallons) daily. If it reads “Alarm”, then use 1 capful for every 200 L (50 US gallons) daily. If it reads “Toxic”, then use 1 capful for every 80 L (20 US gallons) daily.
EXPERT: If using our MultiTest™ Free & Total Ammonia test kit, use 1 capful (5 mL) for every 40 L (10 US gallons) to remove 1 mg/L (ppm) of free ammonia. Alternatively you may employ the following formula for a variety of ammonia and water levels: 0.125AV=m (for volume in liters) or 0.5AV=m (for volume in gallons). A=ammonia concentration in mg/L, V=the volume of water being treated and m=the volume of AmGuard™ to use in mL. For example, to remove 1 mg/L of ammonia in 100 gallons you would use 0.5*1*100=50 mL.
If water temperature is above 30 °C (86 °F) do not use.[source:seachem]
