Hello everyone, I have my 110g up and running, now I'm trying to figure out what to use for rocks/caves. I was thinking about using poly resin or ceramic rocks as an alt to real ones for less weight, and less water disposition. Any ideas on what to use, the tank is an older style and the glass is very thick so weight shouldn't really be a problem, just would like more water to actually be in the tank, thanks for any help
