API Ammo Lock

If your aquarium tests positive for ammonia, you are recommended to act quickly by doing a partial water change and then neutralise the ammonia. Ammmonia is toxic to fish cells, especially the gills, and so API Ammo Lock works instantly in both fresh and saltwater aquariums to detoxify ammonia and remove chlorine and chloramines. A liquid treatment that is fast, reliable and effective, API Ammo Lock locks up ammonia in a non-toxic form until it can be broken down by your tanks biological natural filter, and helps to eliminate fish stress whilst promoting healthy gill function.

5ml treats 38L of aquarium water.

Directions for Use. Use the API Dosing Cap on the Bottle. Add 5ml per 38 litres 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: API 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.
