Stocktank deicer failure

When the severe cold snap hit us the deicer failed and I didn't
notice
since I run it at night. This was the third year for it and I thought
maybe I should get a replacement but didn't. The pond is very clean
but
until I see fish I will worry. This morning I did buy two. The deicer
is thru the ice but the old one is still frozen in with the wire
guard
which I need so I don't put a hole in the liner. The goldfish were
getting about 7" or so and really visable from the house. Nothing
like
surprises.

The timer did not work. It looked like it was on but was not turning
the heater on. The heater got mangled getting it out of the ice but I
will try it tomorrw when it is warmer.
