Questions??

just wondering about starting up a SW tank, i have a 120g tank that i would like to get up and running and was wondering how much LR, and Sand (and type of sand) i should use... im looking towards doing more invertabrates then fish but i still want that vibrant color. As well i would like to know the best sumps and filter that would maximise my out puts. and what lights work and excellent set ups for my tank. im going to try and take some pics of my tank so anyone helping me out will know what their dealing with..

thank you to who ever helps out.
