Tank looks great, but my first thought was that is alot of fish for a 2 month old tank. As I read down I see you are having a few issues. Sorry I have been away from the forum for some time, so I missed the setup process if it is posted.
One thing that might help is if you can update your "my info with more details like kind of filtration. At two months your tank may not even be completely cycled with teh load you have.
Are youe testing the water? If so what are your readings?
Do not give up, maybe just slow down a bit. A new tank is not really established for at least 9-12 months.
Tank: 90 Gal SW Reef in the making
See my info for setup and inhabitant details:
