What Is an Inground 18×36 Pool Cover and Why Is It Essential?

An inground 18×36 pool cover is a protective covering designed specifically for pools measuring 18 feet by 36 feet. This cover safeguards the pool by keeping debris out, preventing evaporation, and enhancing safety by reducing access to the water.
