API Ammo Lock works instantly to detoxify ammonia, chlorine, and chloramines in fresh and saltwater aquariums. Fish continually release ammonia into the aquarium through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia to the water. Even small amounts of ammonia stress fish; large amounts of ammonia will kill fish. Ammonia is the #1 killer of freshwater fish. API Ammo Lock does not remove ammonia from water; it converts it to a non-toxic form. Aquarium water will show a reduction in ammonia on API Test Kits, but a 25% water change is still recommended after dosing. Features: Detoxifies ammonia in aquarium water and tap water Works instantly to make aquarium water safe for fish Reduction in ammonia levels measurable on any API Test Kits Use: For best results, use as directed on the product label. Dose freshwater and saltwater every two days until ammonia is not detected. If your aquarium tests positive for ammonia, do a partial water change, then neutralize the ammonia with API Ammo Lock.
