Setup, Compatibility & Care
To use API Ammo Lock effectively, ensure your aquarium has an established biological filter. Add 5ml for every 38 litres of aquarium water. If ammonia is still present after 48 hours, repeat the treatment until your test results return to zero. Store the bottle in a cool, dry place out of direct sunlight and keep it away from children and pets. This product is compatible with all API water testing products, though it is vital to remember that these tests measure total ammonia, not just the toxic component, which explains why the readings remain high after treatment.
