Premium Blue Rectangle Solar Pool Cover for 18' x 36' Pools

Established in 1982 by a husband and wife team, In The Swim has grown to become one of the largest online retailers for pool chemicals, supplies, and equipment in the country. Starting small, shipping chlorine from the back of their garage and taking orders on their front porch, they quickly realized the potential for something big.

Now, 40 years later, we offer a wide range of products including opening kits, solar covers and reels, hard wall pools and liners, chlorine and shock, salt cells, filter cartridges, water clarifiers, alternative sanitizers, spa kits and covers, algaecides and flocculants, bromine and water balancers, stain removers and cleaners, deck paint and patch, paint and primer, and pool closing supplies.

Our 18' x 36' Rectangle Pool Solar Covers are designed to help heat up your water, with the ability to increase water temperature by 8-10 degrees in just 5-7 days of consistent sunlight. Made from durable polyethylene material, our solar covers are easy to install and can reduce water evaporation, chemical loss, and debris in your pool.

When fitting your cover, be sure to measure your pool's length and width, allowing the cover to settle for a day to ensure it lays flat. Trim the cover to fit any irregular shapes if needed. To care for your cover, handle it with care, wait 24 hours after adding pool chemicals before covering, and clean it thoroughly before long-term storage.

For added convenience, consider using a solar cover reel to simplify the process of covering and uncovering your pool. Choose from a variety of solar covers including Premium, Standard, Premium Plus, and Ultra options.

In addition to solar covers, In The Swim also offers a range of sanitizers including 3 Inch Chlorine Tabs, Cal-Hypo Pool Shock, Bromine Tabs, 5-in-1 Super Multi-Tabs, and Di-Zap 3-in-1 Shock. Our products are designed to keep your pool water clean, clear, and safe for swimming.
