Dwight,
When in full operation, do you think the ripple effect across the pond will result in a much larger ice-free area than anticipated?
Bruce,
In order to combat the protein scum effect, Dwight would have to run this unit during the summer right? Any thoughts on how often and how long he would need to do this? I see a "scum" build up on my little BG pond during the daytime in the dead of summer. After the diffusers run at night, the water looks fine by morning.
