I read a thread once where rocks were installed on top of a PVC
frame. I cannot remember the thread and wish I'd bookmarked it. I read another where 1 1/2" PVC
lengths were cut 1/2" to 1" taller than the sand bed. Holes were drilled into the PVC
and they were placed down in the sand bed so that a 1/2" to 1" was sticking out. The rocks were then placed on top of the PVC
pipes. Rocks sitting on top of egg crates, on the tank bottom with the sand added afterwards, and rocks placed directly on top of the sand beds.
I'm looking for the best installation of rock. Any ideas/suggestions/reccommendations? What's the best way? I want to hear how everyone has installed their rock.
