Hi
I would like to build a greenhouse .
For a <1000gal out ground concrete pond.
We have winter minimum temperature at 15c at night and early morning.
We are raising peacock bass.

Is a greenhouse effective to raise the temperature of the pond or not?
Will or (how can be ) the heat be stocked to save the fish from night coldness?
