Supporting Rocks to Stand Upright
I am interested in setting up a tank with some larger pieces of Dragon stone standing upright. I will cut pieces so they are sitting on a flat bottom but would like to know if anyone has any ideas on how to secure them in this position.
Some ideas I've had are attaching a piece of slate, similar to to the way aquarium driftwood is done but I feel like it would be difficult to find an anchor that would not be easily ripped out of the Dragon stone as it seems fairly soft, as far as stone goes. My other is is pouring some kind of cement/epoxy into a small square form and placing the stone in the middle to create a rigid base.
Does anyone have any experience with this or any suggestions on aquarium safe materials?
