What is a skimmer's function in pool maintenance?

The function of a skimmer in pool maintenance is primarily to remove debris from the water surface. This is crucial for maintaining water quality and clarity. Skimmers work by creating a flow that draws in water near the surface of the pool, capturing leaves, insects, and other floating debris before they sink or contribute to water quality issues.

By keeping the surface clear, skimmers help prevent organic matter from decomposing and creating contaminants that could affect the pool's chemical balance and overall hygiene. Additionally, the debris collected in the skimmer can be easily disposed of, promoting efficient pool upkeep.

While the other functions listed, such as recirculating water, balancing chemical levels, and heating the pool water, are important aspects of pool maintenance, they do not pertain to the skimmer's specific role. Skimmers are directly involved in surface cleaning and play a vital role in the overall health of the pool system.
