    • Works but nothing major
Size: 32 fl oz (Pack of 1)
This is a product I have used for a couple of years. It doesn't maintain the temp perfect but I do see a difference when using it. Don't expect to put this in and have you pool not lose any heat...it will reduce the heat loss but not eliminate it. We normally keep our pool around 82 in the later summer/fall months and if we don't use it we lose about 4 or so degrees on a cool night. If we do use it, maybe we only lose a couple. I think it works good enough especially in those in between months to help reduce heat loss and save your heater or keep you pool a bit warmer until the sun can do it's job. Overall, not bad but cheaper than others and does okay so worth it to me. ... show more

    • Difficult to say if this has had any effect on temperature or water loss
Size: 32 fl oz (Pack of 1)
I've used this product for three weeks and I have my pool filler on a device that measures precisely how much water I'm adding. So far there is no obvious change in water usage, certainly nothing dramatic. Of course it is hard to be certain since temps and wind are highly variable so unless you have very consistent weather and do some back to back trials it would be hard to isolate the effect unless it was very dramatic. Really in terms of water loss my water costs $0.005 per gallon so at current retail prices the 4 floz weekly addition for my pool costs $3 so that would require saving 600 gallons of water over the week or 85 gallons per day. Given my daily average usage right now, with ~100F daily temps is about 100 gal per day I would definitely have noticed that kind of savings. At best I think it could be a few gallons per day. As for temperatures again it is really hard to isolate changing daily temps from any effect this might have but thus far I don't see anything significant. The only really positive thing I can say is this product is undetectable when added to my pool. No sheen or oil feel like people have said. I'm pretty certain those people must have added the entire bottle at once - i've definitely read a few reviews where they mention adding multiple doses and even 16oz at one go. If you're adding more than recommended you're definitely just wasting product for no added benefit. If you add the correct amount to a 400 sf pool the layer will be 3 microns thick. Literally a few thousand or so atoms thick and atoms are very very small. ... show more

    • Doesn't work and increases filter pressure
Size: 32 fl oz (Pack of 1)
This doesn't work well at all. I didn't expect it to be as good as a plastic cover, but this one really didn't do much. I lost 2 degrees with the plastic cover the night before I used this. The first night that I used this I lost 5 degrees. The second night I added more product thinking that maybe the initial dosing wasn't enough. Nope. I lost 1 degree before 11pm. I'm not sure how much I actually lost overnight since I left early in the morning before the pump turned on, but the end of day temperature for day 2 was well below what I was seeing with the other brand of liquid cover. I saw steam coming off of the water both mornings, something that I didn't see with the other brand. I also saw a rise in my filter pressure with this. My clean filter pressure is 10 psi. My filter was at 11 psi when I added this, and then it went up to 13 psi right away. It went up even more when I added the second dose. I have a Hayward cartridge filter. I won't be using the rest of this bottle and will need to figure out how to dispose of it safely. ... show more

    • Seems to do exactly what it says it will.
Size: 32 fl oz (Pack of 1)
I held off writing a review until I had some time with this product. My pool is 25,000 gallons in the mid west. I have been adding 5oz every week for about 5 weeks. The evaporation loss has been minimal. I normally have to add water every couple of weeks, but not at all this year so far. There have been rains, but there are every year. What I was having trouble measuring was the solar blanket portion of their claim. Yesterday my pool was 83, this morning at 7 am it was 79. Our outside had dropped to 55 because of cold front that passed through. 4 degrees, but the interesting thing is that by this afternoon it had climbed back up to 82 under partly sunny skies and a high temperature of 75. I did not run the heater at any point. ... show more
