Well, this doesn't look much different from yesterdays colors does it.
I see you did ghostfeed I missed that before, that might be the source of ammonia.
I would remove as much food as I can find, then I would wait a day or two just to have a clear confirmation that nitrite and nitrate are really not changing (seems likely they wont change as you just said nitrite is 0.25 for weeks).
Then once its kind of confirmed, I would bring down ammonia below 4 with a water change, add a bit of a prime to really make sure that the tank water is 100% chlorine/chloramine free and then add a round of fritz 9 bacteria, that should clear up ammonia.
A side question, where did you get your rocks and sand from? Were those rocks dry or live rocks?
