J ai acheté ce produit et j aime beaucoup, car avec ce poisson la piscine reste chaude et l eau respire alors l eau plus belle.

Though the idea of this product had me very hopeful, it just didn't work. I've own an in ground pool for 5 years so I know that with a normal solar blanket I lose 2 degrees F over night. Without I lose 4 degrees. Using this product I lost 4 degrees every night for 3 weeks. The water is always calm as it is surrounded by a fence. During that time, because I was disappointed with the way it was working,a couple of times, I used my normal solar blanket losing only 2 degrees at night. In addition,while using the fish, there was a constant water line film forming. I never had this problem before and after discontinuing I no longer have the problem. DON'T WASTE YOUR MONEY!

J'ai acheté ce produit par curiosité. Les instructions concernant le fil noir à coupé ne sont pas très clair. à ma grande surprise, oui suite au temps chaud que nous avons eu, l'eau a semblé moins perdre de sa chaleur. Je n'ai pas de toile solaire et l'eau est resté chaude le temps que le poisson était dans la piscine. Je ne crois pas que je vais m'En procurer un de nouveau

I agree with mikeinfinity and poolguy. This product retains heat as well as the conventional solar blanket in my inground 16'x40' pool. Another important point for me was if you cover your pool with the regular solar blanket, debris cannot go through the skimmer. It gets saturated and then falls to the bottom of the pool, so when you uncover it, the bottom is dirty. Therefore, you have to vacuum. I always vacuum on waste, which means I then have to add water and more fresh water means you have to add chemicals. This adds up to a lot of time, work, and money. The fish are an excellent value. I only use my plastic cover if the temperature drops below 15 degrees celcius at night which is generally only early June and late August.

This liquid works and has been proven in independent tests. The film is used in rice patties to retain heat and extend the growing season. It is food grade and undetectable in the pool. All it does is create a thin film to prevent evaporation losses (which is 80-90% of your heat loss in a typical pool). The trick is to get the correct amount of film in the pool (which varies with size). You might need to use more fish...or add the product manually. We use the solar pill version which goes in the skimmer. Here an example of actual data I have measured: Pool temp during the day: 82F. Night air temp : 60F. Pool loss at night (no cover): 7F. Pool loss at night (solar blanket cover): 2F. Pool loss at night (liquid cover): 3F. Our pool is 41x20 irregular shaped. These results are typical for us. Both the solar blanket and the liquid cover make a big difference compared to no cover at all. Using the liquid cover instead of the blanket causes a 1F drop in temp for us. No trouble at all considering that my solar cover is a major pain in the neck...easily costing me 20 minutes on+20 minutes remove+clean up pm every deployment. It costs me $15 per month and is zero hassle. There are other advantages. When it rains the solar blankets are useless unless you dry them off since evaporation off the top causes the same losses as if there were no blankets at all. I see steam rising from my pool with the blankets on and after a rain...bye bye heat! I'm back to the full 7F loss when the covers get wet. On the other hand, the thin film from the liquid cover reforms itself after the rain...and no more steam. So the liquid cover actually works better than blankets whenever it rains...3F compared to 7F loss with blankets. Try the solar pill version if the fish doesn't work. It works wonders for us. Our pool is 81F on august 24... all we have is a solar heater and the pool gets almost no direct sunlight all day....thats with no blanket. I'm ready to put my blankets on free-cycle.
