This had been a great thread, I'm sorta glad it got bumped. I realized that I miss OpieYutts, he hasn't posted here in quite awhile.

The problem with using pond foggers is the fog likes to lay on the water. On a system I built awhile back I used a 5 head pond fogger in a 5 gallon bucket, used a square pce of plastic inside to act as a splash shield. Put two 1 1/2" holes in the bucket lid, 1 for a hose out and the other with a fan blowing into the bucket. It works very well and the people using it are real happy, except for having to clean and or replace the transducer discs regularly.

There are some much better foggers out there, but not as inexpensive.

I gotta try to find Opie.
