With cold temperatures coming in the way in my area of zone 7a northern NJ, I want to start preparing things that will keep my pond healthy over the winter. My pond freezes every winter so this year I want to have some portions of it unfrozen.
So my pond is very small and is a tub, not a liner. It is 4 feet wide horizontally and like 1 1/2 feet vertically and 1 1/2 to 2 feet deep. I currently use a 90gph pump which will definitely not stop my pond from freezing so I am going to take the pump out for the winter. I know there are many things you can put in the pond and each with different effects such as the pond de-icer, pond heater, aerator etc... which one would suit best for my small pond? I prefer not something that will cost me high electricity bills. Are there any ways I can keep a small portion of my pond unfrozen so my fish won't die?
