newbie questions

[mattg]

Was wondering if I can put a clean up crew in before cycling is done?
Why does my water look so blue? Lights?
I have 24#'s of lr in my 24gal tank. Tank looks pretty full though.. is that too much rock?

I put snails and crabs in on the 2nd day I would just make sure you add a little food if you rock is not live or sand in not live. My live rock came from a 8 year old tank so there was plenty for them to nibble on and I think I lost very few of them in the cycle process.
