should I put heater in as well? tia

That's the heater I use in the lily pond with a bubbler. All the fish made
it thru the winter. We've been holding pretty steady around 32F the last
several days and the lily pond is currently 38F. My koi ponds, even after
the 1000 watt heater having power all day is only at 40F. ~ jan
