What test kits are you using.. I prefer Seachem and Salifert.. I know that one of the sponsors are having a deal on Salifert kits right now.. AS for your levels it seems like its still cycling.. Where did you get your LR
.. A good place if you place on getting more is Liverocks.com.. you wont experience nearly as much Die-Off and you will like the hitchhikers and everything much much better.. With a level of 4.0ppm of ammonia it seems high.. Can you have your LFS
double check your levels or verify with another test kit.. If your levels are truely that High maybe another water change as before would be good..
