New 24g Nano Cube, Help & Suggestions Please

[NanoCubeNewbie]

Hello everyone! Santa was very good to me this year and brought just what I asked for. It's a 24 gallon, Nano Cube DX. This thread will show my progress and with your help and suugestions hopefully it will some day be as awesome as most others I have seen on this site.

This is my first SW tank and I would like to eventually like to have all sorts of reef life, as the of the tank will allow. I also asked for this kind of all-in-one tank so that I could keep it as neatly packaged as possible in my office at work. I was hoping that the DX would have adequate filtration and lighting to house most of the possible inhabitants. I'm seeing lots of posts of mods and add-ons and I'm trying to get some advice to see if they are really necessary.

Below I am posting some pics of the set-up so far. I will list the inventory below, but you will see that I have added live rock, sand and pre-mixed SW from the LFS.

Any help you can be with identifying anything you see in the pics would be apprecited, especially the greenish-whitish lichen looking thing and the little redish-pinkish dots.

Thanks! More to come shortly.
