So I get the tank on Friday but it's gonna be SO late that we won't get it out of the van until Saturday. So I need to pick out a substrate. I used live sand from Petsmart last time. It is ok but I really want something w/ a little courser grain so that when my jawfish spits sand its a little heaver and settles faster. What kind and brand have people used I would love a picture because it's worth 1000 words when it all comes down to it this hobby is about looks.
