dry rock vs live rock

[fishlover07]

Can I have no live Rock in a thirty gallon tank and just have dry Rock

All rock and sand will eventually become "live". The live is the beneficial bacteria. Store- bought live rock usually has hitchhikers which can be good or bad depending on what you get.

If I was going salt I would get a little live rock in hopes of some cool hitchhikers

So I can buy twenty pounds of dry rock and have no live rock and overtime it will become "live"

Correct. You have to cycle your tank and all that, but it will become live. It will not grow all the cool purple coralline algae without there being some introduced, which is why a lot of people will at least add some live rock (plus getting hitchhikers) to seed the other rock.
