this month's "Tank of the mounth" how did he get the rocks to stay on the pvc go in a diagonal direction i know that most of the times people drill them but that seem to hard in this instance... ??

I think there was a picture of how some of the rocks were drilled if I remember correctly. I've also seen people use zip ties to secure rocks, but IMO I wouldn't trust it. It may take a while but I'd think the zip tie would eventually deteriorate and fall.

If you secure the PVC into a piece of acrylic or other wide format under-sand structure it will hold at odd angles.

so if you and a wide base you think it will hold barbra even going in a diagonal
