In 1982, a husband and wife team founded In The Swim, starting by shipping chlorine from the back of their garage and taking orders on their front porch. They had a vision that this could become something big.

40 years later, In The Swim remains one of the country's largest online retailers for pool chemicals, supplies, and equipment. We appreciate your business!

In The Swim's Chlorine-Free Oxidizing Pool Shock: Our chlorine-free oxidizing pool shock removes organic contaminants, boosting the effectiveness of existing sanitizers like Free Available Chlorine (FAC) against bacteria and algae. It extends the life of chlorine in the water, reducing overall usage. Use chlorine shock for algae or low chlorine levels, but for cloudy water or after heavy use, our Chlorine-Free Oxidizing Pool Shock is ideal.

Our Recommended Pool Care: - Adjusting and Balancing: Regularly test pool/spa water to maintain optimal chemistry, promoting a healthy environment, saving cost, and reducing pool maintenance. - Sanitizing: Keep water clean using trichlor tablets, along with shock and granular chlorine for maintenance, for a sparkling clean pool. - Treatment: If your pool is not looking perfect, begin by testing the water. Address specific issues such as algae, cloudiness, debris, or other conditions with the needed chemicals. - Pool Safety: Ensure a safe aquatic environment with essential safety equipment, knowledge of local regulations, and pool supervision.
