bro some things cannot take shortcut yeah?
Anyway, just a few points to note.
1. You need live rocks as bio filtration for bacteria to colonize. Which means in your case, you never cycled the tank at all since you added your livestock in the same day as your live rocks.
2. Cycling process typically take 4-6 weeks. Don't add anything into your tank in this period of time. Don't make the same mistake twice. If you are a heavy smoker, you don't die from lung cancer immediately. Same analogy here, the fish may look fine, but you are slowly poisoning it.
3. You sound like you understand the ANN cycle, so stick to it. Wait till ammonia and nitrite levels are zero, and your tank parameters are stable before adding anything.
