The pond contruction started as we moved into the house in 02/2003. During the first spring time in 2004, Blue Heron cleaned up most of the Koi. Following year, as Mike forgot to turn off the water as he was adding some, the chlorine from the water KILLED all AGAIN!!! Blue Heron was still the major enemy.

We then ended up putting fish lines all over the pond so that Blue Heron cannot land onto the ground. I still think putting a greenhousoe over it is THE BEST SOLUTION.
