Wow, that's crazy, I get my live rock from my lfs for $8 a pound, I have a 15g sw tank, I have notice most stores try to rip you off, I went to one store asked how much a light was, she said $250, I told her I saw the same light at another store and she old me she'd give it to me for $195. I started going to this one place I found and he's reasonable, I call him about stuff at other stores and he'll tell me if they're ripping me off(which is most of the time) so I'll check eBay then go see his prices, cause he even tells me to check eBay about stuff he doesn't have in the store, I just want to make sure I'm buying the right stuff
