I had a K&H Floating heater that sunk over the winter and did not keep
a hole in the ice that resulted in death of 35 of my koi.
did any one have a problem like this.
You must have a HUGE pond to keep 35 koi especially over the winter. I assume
the filter was turned off and they died from poor water quality.....Jerri
