Reduce heat loss in your pool this summer with the Therma Swim Liquid Pool Cover! Easy to use and unnoticeable in water!
If you have a vinyl liner, make sure you adhere to the dosage... The first time, we added too much and the liner faded. Otherwise, a good product and helped keep the temperature overnight.
We have been using Therma Swim on our pool for several years. It doesn't leave a noticable film on pool or feel it on our skin. With this, we never need a bulky solar cover for our pool. eztestpools had the best price we could find by far.
