| Winter pond cover
This winter I intend to heat my pond. I have already install an electrical heater and had experimented last spring. It works really well.
To spare some energy I have to cover the pond so I'm wondering what system is the best. Last spring I had problems with a floating cover because I had not enough air exange, so I would like to find a better solution.
The temperature can reach the - 20 C° during a few month and the snow doesn't alow me to use a flat frame over the pond.
My pond is about 4 by 3 meters and 1.5 meter deep.
What material would you use ? polycarbonate, polystirene and polycarbonate, sandwich of wood and polystirene ? others ?
I would like to profit of your experience on this problem, picture will help me too.
Thanks
