To maintain your pool effectively, you'll require several essential chemicals. These include a sanitizer such as chlorine or bromine, pH adjusters to maintain proper balance, an algaecide to inhibit algae growth, and a water clarifier to ensure crystal-clear water.

Preventing algae growth involves a multi-faceted approach. Maintain proper chemical balance, ensure adequate water circulation, perform regular brushing and vacuuming, and apply algaecide as a preventative measure. These steps will significantly reduce the likelihood of algae formation.

Safety is paramount when handling pool chemicals. Always use appropriate protective equipment, including gloves and eye protection. Work in a well-ventilated area, avoid mixing different chemicals, and strictly adhere to the manufacturer's guidelines for each product.
