It took a while but I just got a reply to the email I sent API about Ammo-Lock. The respondent did apologize for the slow reply saying they were backed up due to the busy pond season. Below is the jist of what he said:
"The process to lock ammonia up is a trade secret but I can tell you that it will not affect the development of your biological filter. The addition of the product simple prevents the ammonia from interacting in a toxic manner towards your fish. You can still test it with test kits and it is available and readily processed into nitrite by your establishing bacteria."
So using Ammo-Lock should not impede the tank from cycling. I did reply back to ask 2 more questions:
1) How long does the ammonia stay locked? That is, does the effect wear off after a period of time and the ammonia becomes toxic again.
2) Does it work on ammonia that develops after it is added or only on what is present? In other words, if you add it to a tank, it will obviously lock the ammonia that is currently present but does it have an effect on ammonia produced by the fish later on.
As soon as I hear back, I will post that response.
