I am debating on whether I should cover the pond with plastic or not.

My pond is three years old. I only have goldfish in the pond. Some are
six inches long and some are smaller. I checked the water temperature
today and it is at 48 degrees F. The fish are very active in that they
swim around the pond as fast as they are able. They seem to be all over
the pond continually. In previous years, when the water temperature
reached this low, they stayed at the bottom and I never saw them. I
live in zone 8-9, so I very seldom get ice on the water.

I use a Skippy filter which keeps the water crystal clear at all time.
Because my fish are so active, should I keep the filter running or
should I shut it off. In previous years, I would shut it off about now
and have never had a problem. I stopped feeding them about a week ago.
