Sorry for the hyjack but I gotta tell this funny story about my winter aeration. I had turned my aerator off for a few days in the fall, the pond froze over to about 2 inches thick and very clear ice. Clear ice is the strongest ice. I thought it would be cool to see how long it would take my aerator to melt a hole in 2 inches of ice so I turned it back on at about noon one day. As I went about other chores I kept an eye on the pond. At first I could clearly see bubbles and rising water gushing up against the underside of the ice. But even after several hours the ice had not melted through but instead began to lift up off the water as a huge air bubble was trapped under it. I figured this would last a short while until the ice cracked. Hours later the ice had not cracked and the bubble under the ice had expanded almost all the way to shore. I figured this would last until the bubble hit shore and the air would leak out around the edges. At about 10:00pm the ice in the entire pond was now lifted off the water about 2 feet in the middle, my pressure gauge showed an extra 5 psi under the ice. The whole thing was one giant bubble. I figured this would crack any minute. I wanted to be there when it cracked so I stood on the dock until midnight watching. It still hadn't cracked so I got impatient and got the .22 rifle. One shot out into the center and the whole thing blew into a million pieces. I got soaking wet standing on the dock and ice flew 50 feet up on shore. I went into the house and informed my wife that I blew up the pond.

Gotta get back to fishin!
