No need to be a smart ---, you wouldn't believe how many kids get on this board with no money at all and want to set up a tank.
Can you use baserock? I just cannot imagine setting up a tank with nothing in it, not good for the fish. As long as you have baserock it will function as LR after time. There is a guy that actually sells baserock out of Hawaii, very nice stuff.
Are you asking about HOB filters or can you set up a sump? If you can do a sump then that is the way I would go. I would just make my own if it were me. A wet/dry and a good skimmer and a tank full of good hawaii baserock would make a very nice tank.
Biggest suggestions would be to not skimp on the skimmer, ASM skimmers are very good for the money, but they are in sump models.
