2 tier Reef Cube

A 2-tier reef cube is a type of artificial reef that consists of two stacked layers of concrete cubes. The bottom layer is typically larger and heavier than the top layer, which helps to anchor the reef in place. The two layers can be interlocked to create a more stable structure.

2-tier reef cubes are typically placed in shallow water, where they can provide habitat for a variety of marine life, including fish, invertebrates, and algae. The two layers of cubes create a complex habitat with different nooks and crannies for marine life to live in.
