Newbie needing some help.

[NanoCody]

I'm trying to set up a 20gal for my first saltwater tank and am looking for some live and live rock to jump start the process and hopefully not pick up any bad hitch hickers. If anyone has any they could sell me that would be awesome. I'm in the Dayton area local to brookville. Even just enough to seed some dry rock and a sand bed would be perfect
