4-8ppm is nowhere close to happy fish. The bacteria need something to eat, but nothing even close to that. May not be what you want to hear but a massive water change is needed at those numbers. Fish may be able to tolerate more than many say, but those numbers are WAY out of the healthy zone. Liquid ammonia dosing in a fishless cycle is even less than that.
Truly not trying to make you angry, but many species will be dead pretty quick with ammonia numbers considerably less than yours. I am changing some water at 1ppm.
