Want to set up my first nano reef tank (SPS, polyps & inverts only)

[neorbk]

I need help, badly. I asked some people but they did not helped me out so I came here, hope you guys help me out.
I am going to set up my first saltwater tank. It's nano 24-18-24. Managed a sump which is 24-12-12. This is my first marine tank and reef too. I want to keep SPS & some inverts (only few inverts).
As this is my first tank so want to know how difficult to run a nano tank with a sump attached? I can get LR, LS from LFS.
How frequently do I have to perform WC for this type of tank?

What else I need (equipments) to run this tank properly?

Auto top-off is really important with delicate corals in a nano. That is the only item I consider critical. Eventually you will have to figure out dosing, either manual or automated. With SPS in a nano you will at some point be using 3-4dkh a day.
