live rock formation

[racer1113]

yeah i didnt really know where to put this thread so i put it on here.
so how do you guys make the caves with your live rock... do you use pvc pipe under the rock to make your cave or what. i tried stacking the rock and i dont really get tunnels just little holes kinda. anyways just wondering if anyone has any suggestions...

One way you can do it is simply try building it before putting it in your tank. Gives you an idea how you want to do it.
