yea, my personal philosophy, when it comes to live and base rock, is buy enough to get through the cycle, then add my own to fill out the rest of the tank...
saves a bunch of $$, you get the shapes and sizes you want, and did i mention that it can save you a bunch of $$?
I'm gonna end up with more than i can use in my DT, so i think i'm gonna put some in the sump just to keep it live, and let some corraline grow on it, and then i think i'm gonna start selling it.. its just too pretty, and so much cheaper that whats at the lfs...
