As the summer season approaches, many pool owners are eagerly preparing to open their inground pools for the season. One crucial aspect of this process is ensuring that the water is clean, clear, and safe for swimming. This can be achieved by using the right chemicals specifically designed for opening inground pools. In this article, we will discuss the essential chemicals that every pool owner should have in their arsenal.


Chlorine is a staple chemical in pool maintenance and is vital for killing bacteria and other harmful microorganisms in the water. When opening your inground pool, it is important to shock the water with a high dose of chlorine to eliminate any contaminants that may have built up during the off-season. This initial shock treatment will help sanitize the water and prepare it for regular chlorination throughout the swimming season.

pH Balancers

Alkalinity Increaser

The next chemical you need to consider is an alkalinity increaser. This chemical helps to regulate the pH level of the pool water, ensuring it stays within the recommended range. Keeping the pH balanced is essential for swimmer comfort and preventing damage to the pool equipment. By maintaining the proper alkalinity level, you can prevent issues like corrosion and scaling.

pH Decreaser

On the other hand, a pH decreaser is necessary if the pool water’s pH level is too high. High pH can cause eye and skin irritation, cloudy water, and reduce the effectiveness of chlorine. Adding a pH decreaser can help bring the pH level back to the optimal range, providing a more enjoyable swimming experience for you and your family.

Algaecides are chemicals specifically designed to prevent and control the growth of algae in the pool. Opening an inground pool after a long winter can often result in the presence of algae. By adding an algaecide to the water, you can eliminate any existing algae and prevent future growth. This will help maintain the clarity and cleanliness of the pool throughout the swimming season.


Clarifiers are chemicals that improve water clarity by coagulating tiny particles that cause cloudiness. When opening your inground pool, you may notice that the water appears hazy or cloudy. Adding a clarifier will help gather these particles together, making it easier for your pool’s filtration system to remove them. This will result in crystal clear water that is inviting for swimmers.


Opening an inground pool requires careful consideration of the chemicals needed to maintain clean and safe swimming water. By using chlorine, pH balancers, algaecides, and clarifiers, you can ensure that your pool is ready for the summer season. It is essential to follow the manufacturer’s instructions and consult with a professional if needed. With proper chemical maintenance, you can enjoy a summer full of fun and refreshing swims in your inground pool.
