Thanks for the update and the compliments. As for the chemical you add that reduces evaporation, it's not that new, but a bubble-type solar cover would be better. The chemical forms a thin single molecule layer over the water, essentially a hydrocarbon film that is water soluble at one end and avoiding water at the other end (which sticks out at the surface). The product will work about half as well as a solar cover because it mostly only affects evaporation and not heat conduction, BUT it doesn't work well at all if you've got wind since that tends to push the product to one end of the pool and choppiness at the surface tends to break it up leaving gaps.
