The problem is when I built the pond I had not considered using it year round so where it is doesn't get much sunlight. I used the PVC poles and 6 mil plastic but it's not enough and only makes a few degrees difference even during the day. Question I have is what can I do to improve performance. I would be fine adding another layer outside or inside but with the very limited sunlight I wonder if it will make any difference or if I should try something different?

The bubblers, de-icers and combos are not designed to warm the water or keep the entire pond surface ice free. They’re meant to keep an opening for gas exchange, which is all that’s needed for the fish in your pond.
If your vent does freeze over during extra cold temperatures, simply pour hot water on the ice where the hole once was. It’ll melt the hole back open – and your fish can breathe a sigh of relief!
