Seachem Products-AmGuard Concentrate

AmGuard™ safely, rapidly and efficiently removes toxic free ammonia. It is safe to use during tank cycling and is ideal for treating unexpected emergency situations. AmGuard™ reacts with free ammonia within minutes and 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 no ammonia removing product canfunction and thus a false positive reading will result. Use Ammonia Alert™ or MultiTest™: Free & Total Ammonia to directly monitor levels of free ammonia. AmGuard™ also removes chlorine and chloramines. Sizes: 10 g, 20 g DIRECTIONS: Each level measure per gallon removes 4 ppm free ammonia. To determine how many measures to use, divide the ppm of ammonia present by 4, then multiply by the number of gallons. Do not repeat dosage for at least 24 hours. AmGuard™ may interfere with ammonia kits. If water temperature is above 30 °C (86 °F) do not use.
