SpaChoice 1-Quart 2-Pack Premium Liquid Pool Heater Solar Cover In a Bottle, Liquid Solar Blanket for Pool, Made in USA

Works Great!

As advertised

Helped a lot with heating the pool

I understand the principle. This did not work for me. I put in the prescribed amount. Nothing. Doubled it, still nothing. And in the morning, I could see water evaporating from the pool as steam. I was not able to achieve a single degree in temperature loss avoidance. I was hoping to extend my SoCal swimming experience by a few weeks, but no luck. The ambient temperature has been consistent here, and if anything, warmer days, but cooler nights per the season. It’s the water temp cooling overnight I was hoping to reduce. Nothing for me. I will not be buying this again.If anyone wants to know, the chemical was completely undetedectable while swimming. No residue, no irritation. Unfortunately cooling prevention was undetectable as well.

Not really sure if these work or not but used for when our cover was shredded and waiting for new one to come. Between the two bottles was shorted 5 oz which is one of the weekly treatments.

Wasn’t sure what to expect, has exceeded expectations. Started using in my 20x40 gunite pool in Long Island, ny in early June and it has maintained my pool above 80 for 10 days straight without using my pool heater. I’ve owned this house for 11 years and have never achieved 80 or above without the pool heater during the month of June! Used 8 ounces since my pool is around 35k gallons (4 ounces per 15k gallons).

Really doesn't work as described. My pool lost heat! I read instructions & followed them! Never buying again!

Best product I’ve ever used in the last 3 years. As we live in central Florida we can use our pool most of the year. So if you want a great product that does what is advertised this is worth the money I am very happy with it and will get more for next year.
