AMMO-LOCK is scientifically proven to protect fish cells against ammonia


  • Detoxifies ammonia in aquariums
  • Works instantly

Follow API Easy Care Guide and use AMMO-LOCK when:

  • Addressing Water Solving Problems to neutralize the ammonia

If the aquarium tests positive for ammonia, act quickly by doing a partial water change and then neutralize the ammonia.  Ammonia is toxic to fish cells, especially the gills.  AMMO-LOCK is a liquid treatment proven to protect fish cells from ammonia.  AMMO-LOCK works instantly, in both fresh and saltwater aquariums, to detoxify ammonia and remove chlorine and chloramines. AMMO-LOCK locks up ammonia in a non-toxic form until it can be broken down by the tank's natural biological filter. Eliminates fish stress and promotes healthy gill function.

Treats: 5ml treats 10 U.S. gallons of aquarium water 

Directions: Use the API Dosing Cap on the Bottle.  Add 5ml per 10 U.S. gallons of aquarium water.  Continue to add AMMO-LOCK every 2 days until ammonia is not detected.  If, after 7 days, ammonia is still present, perform a partial water change, service your biological filter and reduce feeding. 

Tip: AMMO-LOCK does not remove ammonia; it converts it to a non toxic form.  After using AMMO-LOCK, your aquarium water will still test positive for ammonia even though it is in a non toxic form which will be removed by the biological filter.
