If you need the extra surface area I'd go with rubble.
Hey essop3, i wana make a pod breeding tank too, how much sand, rock, or what ever is in your pod breeding tank and how big is your pod breeding tank? And is your sand big or tiny sand, and what kind of pumps do you use to pump them back to the main tank? Wont pumps kill the pods whean they go in the pump? Will a 10 gallon work as a pod breeding tank, it will be for the 20 gallon main tank?
