Ammonia levels

[iuman1979]

I recently (10 days ago) cleaned out my whole tank completely. It's a 5 gallon tank, with 2 guppies and 2 danios. The water is now getting cloudy but the ammonia is nondetectable. The nitrites are also nonexistent. I feed them once a day, and I only used StressZyme once. Is this normal? I know my water test kit is fine, I've been using it for the past month with no troubles. It had been registering ammonia before I cleaned out the tank. Could someone please give me some feedback?

By completely cleaned out do you mean emptied 100%?
If you did not rinse the filter or gravel then chances are that there was still nitrifying bacteria alive amongst the filter media etc. This would mean the bacteria had a head start on the ammonia being produced by the fish and hence no ammonia readings now.
In future I would recommend you do just partial water changes on the tank. You will stress the fish less and have a lower chance of sending the tank into a mini cycle.
