Ammonia- 4.0 which didn't change after water change.
Have you tested your tap water? What is the pH of the tap water straight out of the tap, and what is the pH of the tap water, dechlorinated, after sitting in a bucket for 24 hours?
6.4 is ridiculously low for yellow labs. Much too low.
4ppm of ammonia is also ridiculously high. Very dangerous.
Did you learn about the nitrogen cycle, and cycle this aquarium before adding any fish?
What brand is your test kit?
