so im going to be need a whole heck of a lot more sand for my upgrade than i originally thought. here's my plan. i thought maybe i should scrape the top 1/2 inch or so of my current LS off to seed the new sand i get for the new tank and use the rest in my new refugium along with some new sand to make a nice DSB in there. so i'd be needing something like 80-100# or so of new sand for the display tank and 10# or so for the fuge. i was thinking about being cheap and using playsand but im not sure im willing to take that risk. after all im dumping so much cash into this upgrade i'd feel pretty dumb trying to save some $$ going with playsand and regretting it later. SO, it looks like it may actually be cheaper to by "live" sand off ebay then to by aragonite at my lfs (not my super cheap basement guy an actual store). does anyone have any advice for me? any store online i should check out? THANKS! kat
