SunHeater Shield, 32 oz. Bottle – Liquid Solar Blanket, Non-Toxic and Safe for Swimmers, Reduces Water Evaporation Chemical and Heat Loss, SHS32-3, Pack of 3, Clear

I add 1 cup a week to my 25,000 gallon in ground and it definitely raises the temp about 4 to 5 degrees. This summer was a little cloudy and the massive rain storms would have had my pool at around 82 without it. It’s currently at 87! I can only imagine if we had more sunny days above 76 degrees in NJ. It retained heat awesome with the 3 heat waves. On days it was 76 degrees, the pool felt like a like warm tub. I haven’t noticed too much of a savings with the chlorine, but I’m sure it’s there since I had an acid problem that locks the effectiveness, totally unrelated to the product. Saved a ton by not installing a heater or solar blanket that wouldn’t have lasted long. Took 3 bottles from late April till now, midway through Aug. ordered another 3 bottles in hopes I can use the pool through Sept and have some to start next year. Amazing product!

We have had very little rainfall this summer. Even so the water level in my large in ground pool has not fallen measurably. I estimate that this product is good for at least 5 extra degrees, which is enough to matter. I am pleased overall.

Extremely useful

It works but you have to use more then recommended, still beats loosing heat!

Our deep end stayed 4-5 degrees warmer than it ever has in previous seasons with this product. Highly recommend. We live in Wisconsin where summers tend to be short, this made the pool more comfortable sooner in the year, hoping we get extra 2-3 weeks use.

Very easy to use but a cover works better

There is no way to tell if this stuff works my pool still loses plenty thru EVAP. ( New , not leaking). Cheap enough will continue to use

It has been consistantly close to 100 degrees for weeks here. my pool temp hasnt gone above 80. I added more, no change. Cant be sure its working. I will let you know when I can get in the pool consistently....still chilly in this heat.
