Turtle mountainmans acid dispenser thread gave me an idea. To exhaust the fog chamber back into the res. if no exhaust fans can handle moisture what about a submersible pump that can run dry. Some thing like is found in the fogger unit may work also. One fogger could pump in the fog and to relieve the pressure another fogger or whatever could move the fog from the other side of the chamber via tubing to the bottom of the res.

What do you think?
