I own an endless pool and have been taking good care of the water with all the help on this site and my TFT-100. My pool is indoors but we have sky lights in the ceiling. When direct sunlight shines on the water I see a film the surface. Initially I assumed the worse and thought I may have a leak in the hydraulic hoses that pump hydraulic fluid to the motor to generate the swim current. To test this theory, I placed a white highly absorbent piddle pad on the surface of the water to see if I could detect any color, the hydraulic fluid is orange in color. The pad was completely clean. Could this film be some sort of body oils, and if so, is there a product on the market I can to resolve the problem?
PS. I had no clue as to which thread to post this. Sorry if I screwed this up.
