whart would be a good substitute for live rock? I am going to be upgrading my 55gallon to a 110, and will be using the 60lbs from that to get started.
My question is, since I already have some decent live rock goin with lots of critters, algae and other stuff going, what could I use to add with that to fill up the 110 and make more hidey places?
