Yes I've thought about a refigum but for right now Im just trying to get my tank up and running. I have a sump and that might eventually turn into a refigum/sump or something like that. I dont really know anyone else around here who is into making coral reefs in their houses, none of my friends have the money to do it either. The LFS's around here dont even carry the real LS, they say you dont need it, its just an internet thing and tell me to just use Nature's Ocean packaged live sand and its the same thing. So i'm kinda on my own here but thanks for the advice, i'll see if I can find anyone local to san jose, CA
