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.

Perfect for people who take carry on bags flying to beach vacation!
Style: Spray (2 Oz)
THE only spray on sunscreen, that is NOT a 200 SPF, thats less than 3.5 ounces so TSA doesnt confiscate it from bag en route to Cancun. I keep a few in the drawer and take the partially used one from last trip to finish off plus a new sealed one as backup. Smells great and sprays a fine lovely mist so you dont fry. LOVE this product. A GREAT purchase. We dont check bags and its hard to find ANY product in under 3.5 ounce packaging. Sure you can pour sunscreen into bottles that mfg says do not leak, but youll learn the hard way that they DO leak all over the inside of your suitcase. Skip that learning experience and buy COOLA.

Best Sunscreen and Reef Safe
Style: Spray (6 Oz)
I've been using this sunscreen for a couple of years now and this is the one! The lotion and the spray are both great, smell good and are reef friendly and organic. They are pricey but my skin appreciates the extra!

Less chemicals than others and it works! Need to sell a larger version however!
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 0.49 Ounce (Pack of 1)
Easy application and excellent for sun protection! One of the "cleaner" ones with less chemicals, but could be cleaner. The tube is very small, so we only use this for face and use Alba Botanica for body. Last time swimming for 1.5 hours, did not burn, while friends who used other sunscreens on their faces were sunburned. Coppertone, please make a bigger tube!
