As StartrTank said once you see a spike in ammonia you can take it out. I personally would remove it then and not leave in the tank.
Using a pure ammonia source, as link from Hummer4 suggested is also a great way to cycle.
Glad to see you didn't get discouraged from responses in the other thread you started.
I didn't want to start a new thread for a similar question... I have 10g cycling with a raw shrimp. I tested ammonia and its as high as the API test could show. The tank is starting to smell a little. With ammonia that high should I go ahead and take out the shrimp? or maybe the question is CAN I please take the shrimp out!?
