Hi, i'm new to the hobby, and am about to set up a 90gallon AGA (48x18x24), and do not know where to begin with the live rock. i was thinking about getting 2x 45-50lb boxes, but i am not sure what to get and where to get it from. i am more interested in getting large pieces with good porous shapes than getting a huge diversity of life,(but thats always nice too) and as i am a college student, i am on a rather tight budget. im in no rush, any input will be helpful, Thanks.
