Blue Wave NS420 12 mil Solar Blanket for Rectangular In-Ground Pools, 16' W x 32' L x 0.5" H, Blue

I live in Hawaii where it is sunny most days. I found I had to add quite a bit of water to my pool due to evaporation at least once a week, sometimes more in the summer. Since installation of the solar blanket, I haven’t had to add water to the pool yet (it’s been over a month) and had to lower the pool level when we had several days of heavy rain. It was super easy to install and easy to cut to shape (mine is a kidney shaped pool). If you have a rectangular shape pool, it’ll be even easier! The blanket also stopped the dead leaves and debris from my trees from going into the pool. It does warm up the water (my pool is not heated), which is a bonus for me. So if you like your water cool, you will need to remove the cover a couple of days before using to cool it down. Overall, this product works great for reducing the amount of evaporation from the pool and helping to keep the pool cleaner. I highly recommend it. Addendum: Now that I’ve had this cover for a year, I’m disappointed to report that the durability is not great and it has shown signs of disintegration — the bubbles are often found floating in the pool. I did see a video showing the exact problem I’m experiencing. I wished I had seen this before purchasing. Although it states there is a five year warranty, when that customer attempted to talk to the company, he was met with resistance stating the information had to still be in the cover itself. Also there is a prorated amount you still have to pay and also the cost of shipping for them to send a replacement. Something to consider before purchasing this product.

The $130 cover bought at my local pool store was 8mm thick and lasted just 2 years. I live in the northeast so its only used a few months and then stored indoors. Warranty does not cover tears not on the seam. This new cover was less than $80 and is 12mm thick. It is noticeably heavier and stronger. Retains heat well.

Product was as listed and size was perfect. Will see how it hold temp over the months to come.

Do not purchase this product. It fell apart in less than two seasons. Even though the purchase dated June 2023 came with a five year warranty, I was told that my warranty had expired on June , 2025. Really not impressed.

So worth the money. My pool consistently stay in the high 80s-low 90s without using the heater for anything other than for the hot tub. This does cause more pool maintenance as everything likes the higher temps but it's worth it (and you can always regulate the temp by not putting the cover on). Also, the cover helps reduce evaporation, and so reduces water costs as well. This cover will shrink a lot. I cut it very long, let it shrink several inches all around, then re-cut it to just barely small enough. A year later and there's a 2 inch gap all around the cover. Not horrible but not as covered up as I'd like. This will pay for itself in a month or two of running your pool's heater. Update (Feb 2016): This cover is already falling apart, it doesn't look like a trash bag on the side of the road yet, but decent number of the 'packing bubbles' have popped and I skimmed them out of the water and just recently when I rolled it up I pulled it (too hard apparently) and ripped it. I'll see how long it will last until it's more trouble than it's worth. Maybe it will last an entire year? 5-year warranty? Let's see how to cash in on that. That said, I'd still buy another one unless I can find one that will definitely last more than 1 year. The money that I saved not running the heater just this one year easily would have paid for several of these. I never once actually heated the pool. The only time we even run the heater is for the hot tub, and we still had to take the cover off during the summer several times because the pool was too hot. And when we did you could easily see the difference in how quickly the water would evaporate without the cover. I reduced a star because it's only lasted 1 (2 tops) of its supposed 5 years.
