Aqua Blanket - The Liquid Solar Blanket for Pools and Energy Saving Liquid Pool Cover, Non-Toxic and Safe Pool Evaporation Prevention, Greatly Reduces Heat and Chemical Loss AB009-12 (32 Oz)

I use this product religiously in my pool. Not only does it help to keep the chemicals balanced but it also works with the sun to raise the pool temperature about 3- 5 degrees higher than normal.

I have used all of the chemical blankets with varying degrees of success. This 1 works. Normally when my pool is heated and the morning is chilly I would expect to see steam coming off the pool. With this product there is no mist coming up which means the heat is being contained and the water is not evaporating. I have solar heating in my pool got up to 82° last week. We had 4 days of cloudy rainy weather with the temperature dropping into the fifties during the night. The pool dropped to about 70 and when the sun came back out climbed right back up again. I would've expected the temperature drop into the low sixties with other products. I highly highly recommend this product

Great! Wish the increments in the bottle came smaller

I have a 15K gallon pool and 5K gallon jacuzzi, located in southern CA with a solar and gas heat. The pool receives about half-time direct sunlight on most days.(+): It does work and coats the surface of the pool. For 2-3 days, I can maintain a pool water temperature in the mid-70F range with overnights dropping into the high 40F to low 50F. Doesn't affect water quality or chemical balance and to the untrained eye, you wouldn't notice it being in there.(-): After about 3 days, my DE filter must remove all of this, as I can no longer see it staying on the surface and the pool temperatures drop quickly into the night. Additionally, in shallow waters (such as our baja shelf or top step), you can easily see the alcohol-layer and luminescence. It has a chemically-type appearance that I find a little annoying. Most people probably wouldn't notice, but it is noticeable, especially in direct sunlight. If you follow the dosing instructions, you should be good for 7-10 days, but in my experience, once you hit day 3, you need to re-dose. At that interval, the cost isn't worth it.Overall, if you're trying to maintain the temps for a few days without using your heater, this works, but it's definitely not cost effective beyond that.

Does not work. I’ve been using a different brand and that one works pretty well. Usually only drops 1 or 2 degrees each night. This brand dropped 4 or 5 degrees every night. I tried double the amount and still not working.

I think it is helping the water temperature as well as the evaporation rate. I will continue to observe.

As advertised. Comparable to what the big box pool supply stores carry, but for half the price.

I liked the idea of this and even out pool person recommended this kind of product.Doesn't work. So we're back to considering a pool cover.
