I wonder if anyone out there would be willing to share ideas or techniques on aquascaping. What kinds of structures are you guys & gals building and how? In my 12 gal I went to petco and got those plastic sections that look like Roman columns and mixed those in with Tonga branch to elevate the rest of the live rock off of the sand bed. Looks pretty cool! Good water flow and looks a little like an aquatic archeology site. I need some new ideas for the 75 I'm working on so let' hear em.
