In The Swim 18' Round Pool Solar Covers
In The Swim Pool Solar Covers are a great way to help heat up your water. Our solar covers are made from a light-weight, yet durable polyethylene material. They are easy to install, simply by cut the cover to the shape of your pool. In The Swim's Pool Solar Covers will help heat your water temperature up to 8-10 degrees in approximately 5-7 days of consistent sunlight. Our solar cover can reduce water evaporation, chemical loss, and the amount of debris in your water.

Fitting Your Cover
Measure your pool's longest length and width for proper cover size. Allow the cover to settle for a day after unrolling it to ensure it lays flat. Trim the cover to fit irregular shapes if needed.
-
Caring for Your Cover
Handle your solar cover with care to ensure it lasts longer. Wait 24 hours after adding pool chemicals before covering to prevent damage. Clean your cover thoroughly before storing it long-term.
Pool Pro Tips: Reapplying the cover too soon after treatment can cause bubble deterioration. For added convenience, consider using a solar cover reel to simplify the process of covering and uncovering the pool.

Fit great. Heavy duty so I know it Will last a couple of seasons. Inexpensive and works great. Keeps debris out of pool while keeping the heat in the water. Arrived quickly

This worked great to heat our pool, we put it up late in the year and after using this blanket where able to swim in the pool even sooner. Very heavy and durable. Easy to size and install

We've only had this solar cover for 2 days. It's heavy duty, fits great, and it should have our pool heated soon. (We've had rain, clouds, and cool weather). Easy to take off but you almost need 2 people to put back on. Big pool makes it harder. We had one for a smaller pool and that's why we ordered another!

Just got an electric heater this year which has been great. The only issue, no fault of the heater, is that the fall nights are getting too cold for the heat pump to keep up. Decided to try this solar cover to extend our swim time into a NY November. I did not expect much but was ultimately blown away by it. Even with temps where the heater shouldn't work, the cover allowed it to get to the set 95* in a short period of time. As a bonus side effect, it kept all the leaves from clogging the filter/burning up the pump and reduced the massive evaporation issue i was having. Used to have to top off the level every day or two to keep it in the skimmer safe zone. Now the level sits proper without adding cold water which was another part of the heating struggle. Box says made in USA and it is a thick material. The only thing I didn't like is the size wasn't exactly on point. It was a tad too big and has to be bunched up in the middle to fit. Not a huge deal but not perfect.

This cover is pretty thick. It’s bigger than what we needed, but I prefer the sides hang over anyways. Before putting the cover on, the water was very cold. In less than 24 hours, after putting the cover on, the temperature of the water was a lot warmer. It’s a little stiff and is sticking to itself right now, but has we use it, I’m hoping it relaxes more.

Very thick and durable, this solar cover was made to last. We used it this summer on our Intex 18' pool, and it worked great. Other than not being cut totally correct, we adapted and made it work.

Great quality and weight. It stays in place and warms my pool 3-4 degrees during a nice sunny day. The sun is only on my pool after 12 noon. Loses only a degree at night. I’m very pleased with this solar cover. Look guessed to using it in the spring.

It's been my experience that solar covers don't do much to raise the pool water's temperature. They do keep debris out while the season gets warmer.
