Ok, I'm orderinmg my live sand this weekend to set up my tank (FINALLY!!!). I've already got my live rock (50-60 lbs)....well, dead rock I guess...I made a thread a while back about that, if anyone remembers. Anyway, on to my question. I know I'm supposed to epoxy my rock together with aquarium safe epoxy. So, my question is...how many 4 oz. epoxy sticks will I need for this amount of LR?
