Pond in winter
This is our first time trying to winter over gold fish in our small outdoor pond (North Shore, Mass.). I bought a floating de-icer but it's 1500 Watts and none of my circuits seem to like it. So, with the real cold coming I'm looking at options:
- Just count on my pump to keep the water flowing. Worked so far, but it hasn't gotten extremely cold for long. Plus some of the tubing is exposed to (soon to be frigid) air because it feeds through a filter
- Get a 500 watt de-icer, and either unplug the pump OR figure the heather will keep the water warm enough going through the filter?
- Get an aeration kit and turn off the pump. I hadn't realized this was an option until just a few days ago. Does this work without/instead of a de-icer?
