If you want a simple easy to use way to get a good pool water sample out without touching the water yourself--> use a piece of 1/2 or so PVC like a pipette. I have a piece that's about 3 feet long that I use. I just thumb over the top end before putting it into the water, then release my thumb and the water displaces the air inside and I again cover the top end to "hold onto" my sample water as I remove the pvc tube and drop my sample into a big plastic cup. Just like you do with a soda straw, y'know?
