In The Swim: A Legacy of Pool Care Excellence

Established in 1982 by a dedicated husband and wife team, In The Swim has grown to become one of the country's largest online retailers for pool chemicals, supplies, and equipment. Starting out by shipping chlorine from the back of their garage and taking orders on their front porch, the founders had a vision that this venture could become something substantial.

Four decades later, In The Swim remains a trusted name in the industry, providing a comprehensive range of products to cater to all your pool and spa needs. From chlorine and shock treatments to spa kits and covers, 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, as well as opening kits and chemicals – we have everything you need to keep your aquatic oasis in pristine condition.

One of our standout products is the In The Swim Black Algaecide, a specially formulated solution that eradicates stubborn black algae from your swimming pool. Containing 11.8% copper sulfate pentahydrate, our algaecide breaks down the tough defenses that other solutions struggle to penetrate. For the best results, we recommend thoroughly brushing the pool surfaces, cleaning the filtration system, and super-chlorinating the water before adding the Black Algaecide.

This versatile solution can be used as both a treatment and a maintenance algaecide, ensuring your pool stays sparkling clean and algae-free. Please note that due to state restrictions, we are currently unable to ship the Black Algaecide to the following locations: DC, ID, MT, ND, RI, SD, UT, VT, AK, or HI.

Thank you for choosing In The Swim for all your pool and spa care needs. We're proud to be part of your aquatic journey and look forward to providing you with exceptional products and service for many years to come.
