The one chemical I use when mini cycling is water changes with prime. I don’t know much about ammo lock but the water change will drop the am. by whatever percentage you change and the prime will detoxify any remaining ammonia / nitrites for a day to get your inhabitants to the next water change. If your ammonia is that high you should be changing daily anyway. And test your nitrItes. Ammonia may not be your only problem and I don’t think ammo lock touches nitrites, unlike prime.
