Have finally started my new tank after breaking down old one about a year ago. I will be using sand as a substrate which I yet to purchase. As of right now I have my live rock sitting in tank on top of some eggcrate as not to sit on the glass bottom. Was wondering if it is ok to leave the eggcrate in a base for the rock and then fill with sand. Could this lead to any problem with sand stirrers, ie: injuries, getting stuck, or lead to problems with the sand not getting fully stirred in between the grid? Any comments are appreciated. Photos will follow with my progress.
