An aquascape is only as good as its foundation. A pile of rocks balanced precariously WILL collapse, taking corals and livestock with it.

Materials

  • Marco or Pukani dry rock
  • Reef-safe two-part epoxy putty
  • Acrylic rods or zip ties for armatures

Build sequence

Dry-fit the entire scape outside the tank, then disassemble and rebuild with putty between every contact point.
