I would say go with the LS
option, just DONT bother with the "live sand in a bag" at the LFS
. It is highly overpriced wet sand. Just look for Argonite play sand at a Home Depot or Lowes. You can get a 50# bag for $4-5. I find that LS
looks much better, supports a much more diverse pod and worm population therefore making a much healthier and effective substrate. With proper water circulation you'll get little to no detritus settlement on a LS
bottom where as CC will collect much more "gunk" on the bottom of the tank.
