Over time, pool light niches in Stockton pools accumulate mineral deposits and algae that dim illumination. To clean niches, first shut off power and lower the water level below the fixture. Remove the light lens and carefully brush the niche interior with a soft brush and mild acid solution, avoiding lens contact. Rinse with fresh water, reinstall a new gasket if needed, and reseal the fixture tightly. Once the pool is refilled, restore power and test lighting. Professional niche cleaning by Pool Service Stockton ensures corrosion-free fixtures and bright, reliable pool lighting that enhances nighttime enjoyment.
