Hello,
I am setting up a layout with 75% planted gravel and 25 % dead area with sand.
I want to create a small landscape on sand with lava rocks.
My question is if the sand can hold them in place when i fill the tank with water.
Now that sand is wet it can keep the stones in whatever dimension i want to.
Do i need something under the rocks to prevent collapsing?
Thank you
