Sun2SolarBlue 18-Foot Round Solar Cover Heat Retaining Blanket | 1600 Series with 6-Pack of Heavy-Duty Grommets Bundle | for In-Ground and Above-Ground Round Swimming Pools | Place Bubble-Side Down

Just got this solar pool cover and it's a perfect fit for a 21' pool. Very sturdy and already hearing up pool.

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.

This solar cover works so perfectly!! I purchased the clear after researching the color differences. I’m cold sensitive and our pool was stoo cold for me during the hottest days of summer. A friend recommended a solar blanket over other heaters and this cover truly traps heat and warms the water to a very comfortable temperature, like bath tub warm. I keep cover on when not in use with pump running. I turn pump on in the morning 8hrs setting). Restart in mid/late afternoon and again before going to bed. Keeping water circulating for many reasons like all pool owners, but feel this is one of the keys to warming your entire pool from top to bottom not instead of just the surface levels.

I've giving this 4 because it works (so far) may come back to update when we get colder weather for specifics. The lost star is mostly due to the holes that have formed (even though this most-likely is beyond the control of manufacturer). Also a 4 because the actual product does not look like the picture rather it looks like encapsulated-air plastic sheeting and I am not a fan of smoke and mirrors. However, there was a picture of it actually used so at least they had this, but this picture's resolution doesn't capture the first impression of its appearance.In addition: there are some issues that I'm investigating for now just mentioning them, and may update review as I determine them.1. A white film remains on the surface when it dries. I have checked the water PH and Alkalinity, but this may just be calcium or something of this nature from our water.2. When this film mixes with the water the water looks cloudy. I am almost certain the cloudiness of the water and the cover are related, as when it is taken down for several days the water cloudiness gets filtered away. The sand filter has been recently cleaned and the baquacil levels are maintained and confirmed.3. Mysterious holes on random cells have formed. I suspect this occurred from the birds, due to the precise cut of the pierced areas. The rate of new holes has seemed to stopped there are about 10 of them.At the time of this review I've had it for less than a month.

Do not buy from this company!! We bought the solar cover and paid the extra money for the series 1600 and it is so thin like a cheap series 800. I contacted them and they said they can't help me they buy products from all over and that is what you get. I ordered it on Amazon but because I put it on my pool they won't take it back. I know it won't even last a season its that thin. Lesson learned not to buy from this company!! Horrible customer service they don't want to help you. I didn't even want my whole money back just charge me for the cheapest one. BUYER BEWARE!!! In the pics you can see right through it and how thin it is.

Live in Florida and using this blanket with the solar heating is extending swimming season. I have the roller so I take off the pool, rinse and reinstall. Time will tell if it will last but so far so good.

The 1600 series cover appears very sturdy and heavyweight material assure durability but the grommets from the ad never materialized.

Just finished placing it on our 24 foot round pool. We thought it would need to be trimmed, but it came precut, perfect fit, just rolled it out. Seems like a good heavy duty quality. Quick delivery. Highly recommend!
