Cooled our hot pool down about 8

Living in Texas with 100+ temps. our pool was hot.  Got this to help cool the water.  Hooked up easy to our Coleman 18' pool.  Worked great for 3 days then too much pressure on sprayer made the fitting at pump leak.  I took out the turbine in the sprayer to lessen the pressure, no more leak.  The l.e.d.s no longer work but the pool stays cool so we are happy with the purchase.

This fountain is GREAT for cooling down the water during the summer.  Been running it at night and it brought the water temp down 8 degrees after 3 days.
The rotating gate adjustment at the bottom allows the fountain to stay installed during the day by opening it up to keep circulation going.  Then close the gate at night and up goes the fountain !!!

I have two of these in series on my 8' x 30" pool. I have a timer that turns the pump on at 10:30 and off at 6:30. I live in Tampa, so the pool temp is 90-95 at turn off.

Great product!  It actually works!  Living in Texas our pools feel like bath water by mid summer.  This cooled it at least 7-8 degrees!!!!

Purchased our solar cover in April.  The price was great, free shipping.  We cut the cover to the exact shape of our pool.  It warmed the pool up very fast.  In 5 days it went from 80 to 85 degrees. We kept it on our pool for about 4 weeks, to keep the temperature from falling overnight.  It also works good to keep the dust out of the pool.  After the pool warmed up and stayed warm, we dried the cover in the shade & rolled it up like a tortilla. We stored it in a resin yard storage box in the shade on our patio for the summer.
We then started using the solar cover again the end of Aug. to keep the pool temp from dropping overnight.  Well, it started delaminating right away.  We are finding thousands of small plastic circles in our pool.  The company says they will replace but we need to pay shipping both ways and the shipping will be the approximate cost of another cover.  So I think we are going to trash it and order a new one next season.
Pros - Does keep the pool temp from dropping overnight, keeps the water clean and free of debris. You will only want to use this in the spring and fall for a few weeks until the water temp doesn't drop.
Cons - It didn't last as stated, but we do live in Arizona with extreme heat, even in the shade. Lots of debris to clean up when it delaminates, we started to have an algae problem for the first time since we've owned the pool. If you lived in another climate it might last longer. It is heavy once it gets wet.  Will take 2 people to remove it from the water.

I have used it for three days and it is working really well. I attached 275 feet of garden hose to it and the outside temperature was 83 degrees and the water coming out of the hose and into the pool was 107 degrees. I am not sure how long before I see a difference in the pool water temperature. I am happy with the product only downside would be the bulkiness of the garden hose.  I would recommend this product.

I give the product 5 stars. I have a 8,000 gal pool, 5 feet deep in a rectangle shape. I got 6 of them. They don't fully cover but i don't think thats the intention. I ended up finding them at my local pool stor for $30 each.
They flipped the first day with wind BUT it was operator error. I inflated them a bit more and they have not blown over since. Yesterday we had 17mph winds with 30mph gusts and they never moved.

I have no heater at all in my pool. Our water started at 59 degrees by end of day we were at 64. Next day, day 2, water 64 so they held the heat and heated up to 66 another two degrees. Today day 3, its at 68 almost 69. Now, our outside temp has reached 75 degrees max, so I expect when we hit our 80-90 degree weather they will heat my pool to at least 74 degrees.
They also have kept the debris from our wind out. It does collect on the rings, but a simple spray off works.
When we are in the pool we just stack them into 2 piles and let them float.
I think shipping causes all the deflating issues bc I got mine local and all work perfectly.

I live in Nevada desert, dirt and wind and I love this product.

We have a 37' sailboat without installed air conditioning.  This unit is small and powerful enough to cool us down, even though we do have issues with externally covering some of our skylights and side windows to reduce incoming heat.  We do sleep very comfortably at night when the heat outside is still 85 degrees and inside we are down to 70. I did have to create a custom hatch mount for the exhaust vent.

After installing have noticed the heat has dropped inside the room where we installed it, so was worth the purchase

So far we have an added 2 degrees, we are in Texas, trying to keep pool warm for water exercise.

Perfect. In So Cal I can keep the water a toasty 90 degrees.  Word to the wise, take cover off every 3 - 4 days to let pool breath. Otherwise warm water can grow algae.

Good for Texas heat to cool down, but did not last as long as I would have liked.  Glad I ordered 2!

Kept the pool motor cooler and cleaner. Well worth it. It's plastic, but actually that is a plus if your motor is in the sun all day. A metal cover tends to transfer heat from the sun to the motor keeping it hotter.

It works really well so far, it raised the temp. In the pool 4 degrees in one day, I still use a solar cover at night, but so far so good. Now if we could only get a week of sunny weather my pool will be sooooo warm!

It works okay.  We did not have a warm summer and it did not ever really seem to heat up the water in our pool.
