Sun2Solar Blue 12-Foot Round Solar Cover Heating Blanket | 1600 Series with 6-Pack of Heavy-Duty Grommets Bundle | for In-Ground and Above-Ground Round Swimming Pools | Place Bubble-Side Down in Pool

Heats water really well. Took about 2 weeks after last freeze for water to reach swimming temp. Pool was opened early!!!!The most important thing to remember is, if you don't leave it on and circulate the water, it won't work. Let the solar cover cover the water for 3 to 4 days to start the process. Then turn on the pump to blend warmed water with bottom water which is cooler. After about 6 hours of running the pump, turn it off and reheat the water. Only the top 10 inches will receive the most solar heat. That's why it takes about two weeks. But well worth the wait. Just ask my wife..

We bought this originally for a 15' easy set pool at the beginning of the summer and we're still using the same one after upgrading to an 18' pipe frame pool. It made a DRASTIC difference in both heating speed and maximum temperature of our pool water, in both cases. The most important thing is putting the cover back on when you aren't using it, because it starts heating the water as soon as the sun starts coming up in the morning and any level of light is passing through the little bubbles in the cover, even when the air doesn't feel warm on your skin yet, and it also insulates the surface of the water from evaporation and from getting chilled by the cold air (like at night).It was a little too big for the easy set pool, since the top inflatable ring isn't actually the full 15' that the lower liner part fills out to (which is what the pool is labelled based on so it sounds bigger when you're buying it), it's really more like 13', maybe 13.5'. This caused excess material to stick up over the inflatable part, which at first we thought couldn't hurt...it'll just keep debris from getting into the water along the edges, right? Except the part sticking up around the edges would catch the breeze, which sometimes meant we'd find it on the ground when we came outside, and one time a strong wind blew the cover partially off so it was hanging over one side of the pool enough that the weight of it caused that side to collapse and dump 1000-ish gallons of water all over our patio before we caught it. When we didn't have to worry that it might be getting too windy though, it was AWESOME. Our hose water comes out of the well at 54 degrees and that cover raised it to 70 in one full day of sunshine (on not even that hot of a day, like 75 , I live in Oregon) and then reached 81 by day 3 and maintained it even though it goes down to 50 at night in the summer here. If you're looking into getting a solar cover for an easy set pool I would say DO buy one, but get the next size smaller than your pool to make up for the taper in at the top. It's VERY important that this cover is laying flat across the surface of the water and not curving up the side of your pool at all to maintain the surface tension and avoid turning the cover into a sail and/or causing a patio flood.Since upgrading to the bigger pool, it still works GREAT. Sure, this 15 footer doesn't cover the entire surface of the 18' pool, but it still heats the water, and with the new pool being a darker color (a brown wicker pattern compared to the lighter blue of the old easy set pool) it seems to absorb enough extra sun on its own to still sit around 80-82. When it's time for a replacement solar cover due to normal wear & tear I'll probably go ahead and order the bigger one to match the new pool (and I'm assuming at that time I can just get an 18' one since the pipe-frame pool has straight vertical sidewalls instead of tapering like the easy set) but this works well enough to not bother buying another until then.

Works Perfect IF you turn your pump system off at night when air temp is low, your pool will stay much warmer pre-season and post-season!! We uncover the pool during bright sunny warm days to maintain and/or raise higher pool water temps. Direct sun beaming onto the water warms your pool better than ANY cover during a sunny warm day!!! This cover will help "HOLD" the heat IF you turn your pump system off at night when the outside air temp is lower than the waster temp.

I live in FL so this gets plenty of sunshine during the day.this cover has kept my pool at a very easy 10 degrees warmer than the ambient temps.I will only need this during the early spring and fall months to keep the water warm to extend ourswimming season.during our hot summers the water stays about 82 on it's own.we get enough rain during the summer that evaporation is not a problem for me.I highly recommend this product.I had a cheaper one before, It simply wasn't good.I suppose you really do get what you pay for.15 round size.

The product is good. Does it's job.Not easy to install on a above ground pool that has no decking. We buried 3 posts in all. 2 posts right next to the pool in the middle to support the roller because we didn't want to drill holes in the top resin rails of the pool. Then another post approximately 24' out to rest the whole thing on & so one person can roll up the cover & swing it completely out of the way. We are still buying the large hooks to mount on a board fence in close proximity. So when we have guests we can completely remove the cover out of the way. We have the large complete resin stairs but one thing no one tells you about above grounds is: if they are over 18' round & 48" deep, you definantly need some sort of decking around it. If only for easier cleaning.Our pool is 24' round and 54" deep. I can't even see over the tall side of it, and I'm 5' 4". Because the land starts going down there also. Now we need a deck 🤷‍♀️lol. My hubby 😩

First the cover does help in heating the pool and retaining the heat. The two problems I have with this cover (16 gauge) is that it is hard to remove from the pool unless there are two people. Even with two people the cover is difficult to fold, heavy and very hard to drain the water off the top of the cover. This bring up the second problem, because the seams are sewn with heavy thread water finds its way to the top of the cover via the stitching. This present the problem of the cover always having water on top of it making the cover heavier than normal when removing it from the pool. I my opinion the manufacturer should find a way to seal the seams.

2 people together had a hard time removing this cover. So we cut it in 3 equal parts and it was still too hard to get out of pool. And we didn't notice a big temperature change. We threw it out, put our blue cover back on, and was so grateful for the easy to put on blue one. And the blue light one heats up the pool just fine. The problem is the clear one was 16 mil and the blue one was only 8 mil. Higher the mil, the heavier the product.
