So I am very happy with the Cover Free Liquid pool cover but not happy with the price and lack of alternatives. I don't like the fact that I am usually having to buy this stuff at the pool store with no alternatives. I actually looked up the patent to learn about what makes this stuff tick.
Now I am no expert here, so please correct me if I am wrong. The main ingredient is a chemical compound called Polyoxyethelene. Apparently this creates a thin layer of a clear "oil" that sits on the water's surface and keeps in heat and dramatically reduces evaporation. So I was hoping I would be able to go online and purchase a much cheaper substitute for the liquid cover. After much searching, I have not been able to find anything that would be a good substitute, but I am convinced that someone with a much better grasp of Chemistry could figure out some cheaper alternatives.
I was just curious if anyone has figured out any cheap liquid cover ideas. Please post them here!
