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.
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.
