Seachem AmGuard removes ammonia in aquarium very quickly. Free ammonia is toxic, and it kills fish and aquatic livestocks. This is why the level of free ammonia in water must be closely monitored and not be allowed to rise to a dangerous level.

Seachem AmGuard works rapidly to detoxify free ammonia in water. It is also suitable for emergency treatment whereby ammonia levels has reached dangerous level and needs to be removed as quickly as possible to protect the fish and aquatic livestocks.

Unlike competing products, Seachem AmGuard converts free ammonia into a safe, non-toxic form that is readily removed by the aquarium biofilter. Most importantly, Seachem AmGuard does not alter pH.

Benefits of Seachem AmGuard

Safe

Does not alter water pH

Ideal for tank cycling and emergency treatments

The strongest liquid ammonia binder on the market

Works within minutes to detoxify free ammonia

Lasts up to 72 hours per treatment (twice as long as most competing products)

Also removes chlorine and chloramines

Ammonia Control

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.

Directions

Use 1 capful (5 mL) for every 200 L (50 US gallons) daily or as needed to reduce ammonia.

If water temperature is above 30 C (86 F) do not use.

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 litres) 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.

FAQ

When should I use AmGuard and why would I use it instead of Seachem Prime?

A: AmGuard is ideal for use in emergency ammonia spike situations. It will bind with ammonia for up to 72 hours and can control ammonia at higher concentrations. AmGuard will also remove chlorine and chloramine but Prime has a wider range of benefits.

If AmGuard is removing ammonia from the system, won't that starve the beneficial bacteria?

A: AmGuard does not remove ammonia from the system. It simply binds ammonia making it harmless to the inhabitants and still bioavailable to the beneficial bacteria.

Is AmGuard for freshwater or saltwater?

A: AmGuard can be used safely in both freshwater and saltwater systems.

Is it possible to overdose AmGuard?

A: AmGuard is very safe and quite difficult to overdose to the point of harming tank inhabitants, but a large enough dose can start to deplete the system of oxygen. The standard dose of 5 mL per 50 gallons of water is recommended for general ammonia control, and higher doses can be calculated to deal with elevated ammonia levels (always dose according to a known level of ammonia in the system). There are a few situations where caution should be taken with elevated doses though:

Your tank is already low in oxygen : A tank with an exceptionally high bio-load, high temperature, or poor circulation is likely quite low in oxygen, so reducing the oxygen any further may be dangerous to tank inhabitants. In this case, using a half dose of Prime or increasing the oxygen content of the tank is recommended.

You are using another product that also reduces oxygen : Most conditioners that clear away chlorine and chloramine, products that detoxify ammonia and nitrite, as well as some medications will reduce oxygen levels in the tank.

Will AmGuard affect my pH, KH, or GH?

A: No, AmGuard will have no impact on the pH, KH, or GH of the typical aquarium.
