Any unit which can be attached to the hot shoe should work. I would 
suggest putting a hot shot to pc adapter on the realist and connecting 
the flash with 3 to 4 foot pc cord. Hold the flash away from the 
camera so fog won't be reflected directly back into the lens. 
Set the shutter to 1/25 sec. It takes the blubs a momment to get 
to full brightness. The bulbs burn slower than electronic flash 
and movement of water provides a nice effect.
I wired a pc cord directly into my flash unit.  Chis Howe has some 
circuits for bc flash units in his "Cave Photography" book.
