Seachem AmGuard

Seachem AmGuard detoxifies free ammonia for up to 48 hours, making it ideal for emergency situations and safe to use during tank cycling.

  • Detoxifies Ammonia for up to 48 hours
  • Ideal for emergency situations
  • More effective than any other ammonia-binding product
  • Most concentrated product on the market
Seachem 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™ orMultiTest®: Free & Total Ammonia to directly monitor levels of free ammonia. AmGuard™ also removes chlorine and chloramines.
Why It's Different

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 forty-eight hours. That’s nearly twice as long as our competitors’ products.

Directions

BEGINNER: Use 1 capful (5 mL) for every 200 L (50 gallons*) daily or as needed to reduce ammonia. (Note: The 2 & 4 L container’s cap is 10 mL). ADVANCED: If you have an Ammonia Alert™ that is reading alert, then use 1 capful (5 mL) for every 400 L (100 gallons*) daily. If it reads alarm, then use 1 capful for every 200 L (50 gallons*) daily. If it reads toxic, then use 1 capful for every 80 L (20 gallons*) daily. EXPERT: If using our MultiTest®: Free & Total Ammonia test kit, use 1 capful (5 mL) for every 40 L (10 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 the water temperature is above 30 °C (86 °F) do not use it.

Lemon: Very weak, almost undetectable
Scent: Lemon
I’m not impressed. I ordered the “Lemon” and it’s nothing like the “Aloe & Green” Tea we had at work. Unfortunately Amazon mixes the reviews together, so you can’t tell which scent actually got the good reviews. I can barely smell the lemon and I have to try really hard. And I’m someone who prefers soft scents that are not overpowering, because I have a sensitive nose. I can’t deal with strong perfumey stuff. But I would like to at least smell something. I remember the Aloe & Green Tea has a nice soft scent, that I could actually smell. So I’m not sure what’s going on with the lemon, unless I got a dud. I’m having a hard time believing this is how it normally is. I’m going to get some opinions from my guests and see if they can smell it.

Such a fresh clean scent
Scent: Ocean Breeze
Such a clean fresh scent Doesn't have all the toxic chemicals in most room sprays. I have been using this for years. One spray freshens the room.

Great for sensitive skin, cleans well.
Scent: Unscented, Size: 4 Ounce (Pack of 2)
Only soap I can use at the moment. I have extremely sensitive skin: I cannot do really any coconut derivatives or even palm oils but this soap does not bother me at all. I feel clean with no heavy scents afterwards (I use the unscented version) which is a win in my book. I don’t use it on my face or hair just as a body soap and it doesn’t make my skin feel prickly or give me any unexpected rashes/reactions. It is a little drying for eczema prone skin so I just use more lotion when necessary. You get two very large bars that last well for the price it seems reasonable, but honestly I’d pay anything to not itch at this point.
