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 can function, 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.
This is for the 500ml bottle, others sizes are available either in store or by request.
