I am keeping 2 red eared turtles, a mystery fish (he's from San Marcos), a bunch of Gambusia affinis, and a few X. helleri in a pond in my backyard. And recently there has been a clear, white film on the surface of the water. I keep it well filtered but the only way I can get the film out is with a brine shrimp net (this takes about 20 minuets to do). What is causing this and how do I get rid of it? My water quality is high.

Often this is a "protein slick" that is easily removed in a tank by soaking it up with paper towel. However, since you have a pond, that will make it tougher to deal with. Do you have anything breaking the surface tension of the pond? If you don't, it might help out to get some sort of bubble action going somewhere in the pond.
I have a sump filter and a waterfall cycling the water in the pond. It goes into areas of low flow though. It came when I started using a solar blanket to keep the pond warm at night. Maybe there's something in it that's polluting the pond (I wish protein skimmers worked in freshwater).

Well, whatever it was it went as fast as it came. I closed up the pond right before the cold weather hit (anytime it's 75 degrees in El Paso during this season it's going to freeze the next day). I did some research and found out that the food I was giving the turtles was high in oils and was causing the film.
