A mountain that moves

Make sand fall like water.

Stacked stone shelves climb in tiers above a sculpted basin. Add an air pump and fine sand, and the sand spills from ledge to ledge into the basin below, a slow-motion waterfall that becomes the moving centrepiece of your tank.

The detail

The Thunderstone Rockscape Resin Sand Waterfall stacks weathered stone shelves into a tiered tower with a sculpted basin at its base. Pair it with an air pump and fine sand, and the sand is lifted to the top and spills from ledge to ledge into the basin below.

Why aquascapers choose it

  • Moving sand waterfall. With an air pump and sand, the cascade runs continuously into the basin.
  • Striking standalone rockscape. Looks great even without the waterfall running.
  • 100% aquarium-safe. Inert and fish-safe, won't change pH or hardness, never leaches tannins.
  • Sinks on its own. No soaking or weighting; far lighter than real rock.
