Established in 1982 by a husband and wife team, In The Swim has evolved into one of the country's largest online retailers for pool chemicals, supplies, and equipment. Beginning with a humble operation shipping chlorine from their garage and taking orders on their front porch, the founders had a vision that this venture could become something significant.

40 years later, In The Swim continues to be a trusted source for pool enthusiasts across the nation. From chlorine and shock to spa kits and covers, the company offers a comprehensive range of products to meet all your pool and spa needs. Customers can easily navigate the user-friendly website and explore various categories, including Salt Cells, Filter Cartridges, Water Clarifiers, Alternative Sanitizers, Algaecides and Flocculants, Bromine and Water Balancers, Stain Removers and Cleaners, Deck Paint and Patch, Paint and Primer, Hard Wall Pools and Liners, Solar Covers and Reels, and Opening Kits and Chemicals.

The In The Swim Pool Calcium Hardness Increaser is a crucial product designed to address low hardness levels, preventing aggressive water behavior. When calcium levels fall below 200 ppm, the water can become corrosive, extracting minerals from pool surfaces and causing etching and corrosion. The Increaser helps raise levels to the ideal 200-400 ppm range, containing 97% granular calcium chloride. A dosage of 6 lbs per 10,000 gallons can raise levels by approximately 50 ppm.

In The Swim's Recommended Pool Care guidelines emphasize the importance of regular water testing and maintaining optimal chemistry to promote a healthy pool environment, save costs, and reduce maintenance. The guidelines cover key aspects such as Sanitizing, Treatment, and Pool Safety, ensuring a clean, safe, and well-functioning pool.

In addition to the Calcium Hardness Increaser, In The Swim offers a wide range of water sanitizers, including 3-inch Chlorine Tablets, Cal-Hypo Pool Shock, Bromine Tablets, 5-in-1 Super Multi-Tabs, and Di-Zap 3-in-1 Shock. These products are designed to effectively sanitize and maintain the water, with high customer satisfaction ratings.
