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.

Budget friendly satin pillowcase
Size: Standard (20" X 26"), Color: 18 - Lavender, Number of Items: 2
This satin pillowcase is a great budget-friendly option! While it’s not quite as luxurious as my Blissy pillowcase, it still does a really nice job—especially for the price. It has that smooth, silky feel that helps reduce hair frizz and feels gentle on the skin. It’s also easy to wash and holds up well, which is perfect for everyday use. I especially love using these for the kids—they get the benefits of a softer pillowcase without worrying about ruining a more expensive one. Overall, it’s a solid, affordable alternative that still feels nice and does the job. Great value and perfect for families!

Super soft and durable, but keep your steamer handy!
Size: King (20" X 36"), Color: 01 - Silver Grey, Number of Items: 2, Size: King (20" X 36"), Color: 01 - Silver Grey, Number of Items: 2
I’m really impressed with these grey satin pillowcases! First off, the packaging was adorable, making them feel like a little treat to unbox. The texture is incredibly soft and feels great against my skin. In terms of maintenance, they’ve held up perfectly through the wash. I followed the instructions (machine wash on gentle cycle and tumble dry on low/fluff), and they came out looking as good as new. The only real downside is the wrinkling. Even when I remove them from the dryer promptly, they tend to wrinkle pretty badly (see attached photo). If you don't mind a quick steam or a few creases, these are a good value!

Fantastic satin pillow cases for the price
Size: Queen (20" X 30"), Color: 02 - Pure White, Number of Items: 2
Edit: I already put five stars in the first place, but I was unfair to these pillow cases in my initial review! I thought they were a little warmer than the natural silk, because I was sleeping on them with acrylic pyjamas on. I have come to realise the pillow cases are not warm. They are truly excellent in every way. I just get sweaty every time I wear acrylic pyjamas! I have already ordered two more sets of these (and have switched to micrfibre pyjamas)! Original review: First off, I want to address a popular misconception. Satin is a weave, not a fibre. So polyester satin is real satin, and it is very common. To all the people saying the makers lied about the fabric, they absolutely did not! I bought these and I bought some inexpensive silk ones at the same time. I have been loving the silk ones and only started using these lately. I'm happy with all of them. These are not silk, and I can feel the difference, but they are a nice, smooth polyester satin. The white colour is indeed a pure white. I machine washed mine and hung them to dry. They did not wrinkle, pick or pill, and they did not change in colour or size. They look fresh and pristine. I measured my pillows and got the right size. They are pretty and neat, they seem to be well sewn and well finished, with no hanging threads. They are very soft to sleep on and did not make my dry, curly hair frizz up. I slept on them without my protective bonnet, so I got the full experience! Honestly, with the smooth, tight weave of the fabric, they may be superior to the real silk in terms of babying my skin and hair. However, they are a little bit warmer. That is fine for now, since the weather is cool. I might just use these while it is cool out and switch to silk in summer, or I might continue to alternate, we will see. Overall, I am happy with my purchase and would buy them again.

Amazing Pillowcases — Sleep Better Every Night!
Size: Queen (20" X 30"), Color: 05 - Dark Grey, Number of Items: 2
The Bedsure Satin Pillowcases (2-Pack) are hands-down one of the best small upgrades I’ve made to my sleep routine. They feel luxuriously smooth — almost like silk — but are much more affordable and easy to care for. The satin surface feels gentle on your skin and hair, and I really notice the difference in reduced friction compared to regular cotton cases. What I love most: 🌬️ Cooling & Comfortable: These pillowcases stay cool and breathable all night — perfect for hot sleepers or warm weather. 💁‍♀️ Hair & Skin Friendly: My hair isn’t as tangled in the morning, and my skin feels softer with fewer sleep creases. 🛏️ Beautiful & Practical: The dark grey color looks great with my bedding, and the envelope closure keeps the pillow snug without zippers to snag hair or wash fabrics. 🎁 Perfect Gift: Comes as a 2-pack and makes a thoughtful gift for anyone — women, men, roommates, or newlyweds. They wash well and hold up without pilling or losing their silky feel. Great quality at a great price — these pillowcases are definitely worth it if you want a little luxury in your everyday sleep!

These pillowcases are honestly a great purchase. They feel incredibly smooth and soft and I noticed a real difference in both my hair and skin! my hair is less frizzy in the morning, and my skin feels softer. The quality is excellent for the price, and they’ve held up well after several washes without losing their softness or color. They also feel cool and comfortable throughout the night, which is a nice bonus. Overall, I’m really happy with this purchase and would definitely recommend them to anyone looking to upgrade their sleep experience!
