You mean to hold it off the sand?
Would you have sand within the PVC
itself? Luckily, I happen to have a big piece of 4" PVC
, which would be great for this, since a few of my rocks are larger, and balancing them on even several 2" PVC
pieces might be unstable.
Is it better to have the rock supported this way, resting on both sand and the PVC
, or to have it just off the sand?
I've heard of this, of course, but I've also heard of people sinking the rock down into the sand... for stability. But now I've got so much sand, several pieces are almost completely buried.
I'm just trying to get the most efficiency out of the DSB
, plus make the most of my LR
