A friend of mine had some nozzles on his pool that he called "rain effect" nozzles. When water was diverted through these nozzles they basically threw up a fan shaped curtain that arced from one side of the pool to the other. It greatly reduced the temperature under the curtain and the droplets/mist were cool as they came down on you. Anyone have any idea where I might find something like this. I checked with my friend, but unfortunately the pool installer that put his pool in is no longer in business. From what I remember the nozzles where a black plastic and looked like they had a whistle shaped opening cut out of them. I guess if I can't find any I could attempt to make some.
