BioGuardSmart Shield, 1 Quart, Ultimate Pool Water Conserver for Long-Lasting Results, Conserves Water Lost to Evaporation

I have used this product for several years. Works well. Reduces temperature drop and evaporation.

Is a good product.

Keeps the water warm!

We went to try it and noticed the bottle was 12 ounces low. Got in contact with Google, they said send it back. At over a dollar an ounce they are trying to rip people off. The seal is still on. Wanted to use it today since it's cooling down. If their quality control is this bad the product can't be uniform.

I put this in the pool this summer as opposed to the aquapill we normally use. I'm not sure this chemical solar blanket made a difference, the pool temperature was always colder than expected, but maybe that was just the weather. The pool needed topping off every couple of weeks too, which I didn't need to do last year with the aquapill.

Easy to use and much easier than taking a solar cover off and on.

Worked as advertised

The shield works for a couple of days and then we had to put our original cover back on… We did try the process twice just to make sure. Again, it appears to work for a couple of days and then our original solar cover needed to go back on.I did consult with a pool professional company and they stated, they have not had great reviews with the product themselves. And the water is definitely cloudy after you use it which is stated on the bottle. You might like the product, for myself, it just felt odd and a bit toxic and I will not use it again

Smart shield pool liquid blanket, works wonder , keeps my pool water temp, won’t effect skin, or your eyes . Been using it for two years now love it .
