Ammonia in new tank vs. pH

Question
I have a new freshwater 10 gal. aquarium. 10 days ago I added 3 fish (2 gouramis and a danio). The fish are doing great. The water is a little foggy but I expected that due to bacteria bloom. As I expected, the ammonia (I have a test kit that tests for ammonia as NH3/NH4 in ppm) has been high. 3 days ago the ammonia was a little higher and the water was getting progressively more alkaline. I did a 1/4 tank water change. After that the water was acidic (about pH 6.3) but the ammonia test still reads in the stress zone (about 2.5 ppm). I'm a chemist and I know that the low pH indicates that the ammonia is mostly in the ammonium ion state. I've read that ammonium (NH4) is not harmful to the fish, and they seem happy as can be. Should I be concerned?
Should I do anything else? Just now I did a reading and it was: pH 6.2, NH3/NH4 approx. 3.0ppm. I have not read anywhere about the ammonium being high during the cycling process.
(Sorry to be so long).

Answer
Hi Moureen,
Thank you for your letter. The main thing that raises the pollution levels and clouds the tank is over feeding. Figure one flake or pellet per square inch of fish per day. If you are feeding more than that, it could cause the high pollution levels.
Here is my page for holistic aquarium care:

Overfeeding will start to turn the water cloudy and viscous and then the fish will die. To prevent this, follow my system - reduce diet & use the product "Cycle" to break down fish waste & protect the fishs' digestion and silky coats. Please read & print out my aquarium page for future reference.
Write back if you want to discuss further.
