PVC rockwall

[Cyberblack98]

Does anyone have any good links or instructions for building a rockwall with caves out of PVC. I have come across some videos and instructions with limited detail but would like more detail. Such as set ups that deal with water flow and dealing with return holes in the back of the tank and positioning of the rockwall in relation to said return holes

Yes I just finished my PVC background. Look up my previous threads to see some pics. I got my idea from YouTube, search for brimi925 he has an excellent DIY video
