I screwed a regular 1.5 inch pvc elbow into my return and aimed it away from my skimmer and slightly down. I now have an amazing whirlpool that moves the surface water as well as most of the other water. I had an eyeball fitting but it was way too restrictive for my liking and it didn't aim as nicely as the elbow!
Awesome idea Beens. That is what I am going to do. Probably only cost $2.00
